Claim	A liquid drug transfer device (50A; 50B; 50C; 50D; 50E) for secure telescopic snap fitting on an injection vial (10) having a longitudinal injection vial centerline (11) and including a closed end vial tube (12), a tubular vial crown (13) having a crown opening (14) stopped by a vial stopper (22), a vial neck (16) intermediate the vial tube and the vial crown, a vial shoulder (19) intermediate the vial tube and the vial neck, the vial crown having an uppermost vial crown rim (17) towards the crown opening and a lowermost vial crown rim (18) towards the vial neck, the vial tube and the vial shoulder meeting at an uppermost vial tube rim (21), the vial tube having a vial tube outer diameter d1, the vial crown having a vial crown outer diameter d2, the vial neck having a vial neck outer diameter d3 and a vial neck inner diameter d4 wherein d1 >d2>d3>d4 and the vial tube outer diameter d1 being selected from a predetermined range of at least one vial tube outer diameter d1 for the vial crown outer diameter d2, the liquid drug transfer device comprising: (a) a vial adapter having a longitudinal vial adapter centerline (31) and including a vial adapter top wall (32) transverse to said longitudinal vial adapter centerline, a substantially cylindrical skirt (33) downwardly depending from said vial adapter top wall for telescopically slidingly receiving the vial crown therein, and a hollow puncturing cannula (34) for puncturing the vial stopper, said puncturing cannula having a puncturing cannula tip (37) with at least one flow aperture (38) for accessing the vial tube, said skirt including i) at least two non-adjacent vial retention flex members (41; 61) having vial retention flex member tips (43; 66) distal to said vial adapter top wall, each said vial retention flex member having an at least partially circumferentially extending inwardly protruding vial retention rib (46) for snap fitting over the vial crown for vial retention purposes, and ii) at least two non-adjacent vial guidance flex members (51; 71) being at least as long as said at least two non-adjacent vial retention flex members and having vial guidance flex member tips (56; 76) distal to said vial adapter top wall; and (b) at least one fluid transfer port (36) in flow communication with said puncturing cannula, characterised by said at least two non-adjacent vial guidance flex members (51; 71) each having a hinged zone (52; 62; 72) located therealong distanced from said vial adapter top wall thereby dividing each said vial guidance flex member into an upper vial guidance flex member section (53; 73) proximal said vial adapter top wall and a lower vial guidance flex member section (54; 74) distal said vial adapter top wall, said at least two non-adjacent vial guidance flex members being outwardly radially hinged at its respective hinged zone (52; 62; 72) relative to the longitudinal vial adapter centerline (31) on said vial guidance flex member tips (56; 76) contacting the vial shoulder (19) on telescopic snap fitting said vial adapter on the injection vial (10). A liquid drug transfer device (50A; 50B; 50C; 50D; 50E) for secure telescopic snap fitting on an injection vial (10) having a longitudinal injection vial centerline (11) and including a closed end vial tube (12), a tubular vial crown (13) having a crown opening (14) stopped by a vial stopper (22), a vial neck (16) intermediate the vial tube and the vial crown, a vial shoulder (19) intermediate the vial tube and the vial neck, the vial crown having an uppermost vial crown rim (17) towards the crown opening and a lowermost vial crown rim (18) towards the vial neck, the vial tube and the vial shoulder meeting at an uppermost vial tube rim (21), the vial tube having a vial tube outer diameter d1, the vial crown having a vial crown outer diameter d2, the vial neck having a vial neck outer diameter d3 and a vial neck inner diameter d4 wherein d1 >d2>d3>d4 and the vial tube outer diameter d1 being selected from a predetermined range of at least one vial tube outer diameter d1 for the vial crown outer diameter d2, the liquid drug transfer device comprising: (a) a vial adapter having a longitudinal vial adapter centerline (31) and including a vial adapter top wall (32) transverse to said longitudinal vial adapter centerline, a substantially cylindrical skirt (33) downwardly depending from said vial adapter top wall for telescopically slidingly receiving the vial crown therein, and a hollow puncturing cannula (34) for puncturing the vial stopper, said puncturing cannula having a puncturing cannula tip (37) with at least one flow aperture (38) for accessing the vial tube, said skirt including at least two non-adjacent vial retention flex members (61) having vial retention flex member tips (66) distal to said vial adapter top wall, each said vial retention flex member having an at least partially circumferentially extending inwardly protruding vial retention rib (46) for snap fitting over the vial crown for vial retention purposes; and (b) at least one fluid transfer port (36) in flow communication with said puncturing cannula, characterised by said at least two non-adjacent vial retention flex members (61) each having a hinged zone (62) located therealong distanced from said vial adapter top wall thereby dividing each said vial retention flex member into an upper vial retention flex member section (63) proximal said vial adapter top wall and a lower vial retention flex member section (64) distal said vial adapter top wall, said at least two non-adjacent vial retention flex members being outwardly radially hinged at its respective hinged zone (62) relative to the longitudinal vial adapter centerline (31) on said vial retention flex member tips (66) contacting the vial shoulder (19) on telescopic snap fitting said vial adapter on the injection vial (10); and each said hinged zone being further displaced therealong from said vial adapter top wall (32) than its at least partially circumferentially extending inwardly protruding vial retention rib (46) such that each said vial retention flex member is outwardly radially hinged at its respective hinged zone relative to the longitudinal vial adapter centerline (31) on said vial retention flex member tips (66) contacting the vial shoulder (19) on telescopic snap fitting said vial adapter on the injection vial (10). The device according to claim 1 wherein said at least two non-adjacent vial guidance flex members (51; 71) each have said hinged zone displaced therealong at the same distance from said vial adapter top wall (32) as said at least partially circumferentially extending inwardly protruding vial retention ribs (46) such that, on telescopic snap fitting said vial adapter on the injection vial (10), said at least two upper vial guidance flex member sections (53; 73) and said at least two vial retention flex members (41; 61) snugly encircle the vial crown (13) in a uniform manner for each vial tube outer diameter d1 from the predetermined range of at least one vial tube outer diameter d1. The device according to claim 3 wherein each said vial guidance flex member (71) subtends a sector angle of at least 90° around the longitudinal vial adapter centerline and includes a pair of spaced apart lower vial guidance flex member sections (74). The device according to any one of claims 1 to 4 wherein a said hinged zone is constituted by an external peripheral groove (57; 67). The device according to any one of claims 1 to 4 wherein a said hinged zone is constituted by two or more spaced apart hinges (58).
