A vial adapter (100) is provided for interconnecting a vial (300) having a closure (320) and a fluid delivery device such as a safety syringe (400). The vial adapter (100) comprises an adapter housing (110) having a base (120), a shroud (130) extending or projecting from the base (120) and a cannula (150) extending or projecting from the base 120) for penetrating a rubber seal (330) on the vial closure (320) to thereby establish fluid communication between the vial (300) and the vial adapter (100). The shroud (130) may comprise a plurality of latitudinal slits or windows (131) within each of which resides a flexion arm (132) connected to the shroud (130), each flexion arm (132) capable of engaging and/or retaining vial closures (320) of any of a variety of different sizes. The vial adapter (100) may comprise a conduit tip (160) in fluid communication with the cannula 150) to allow transfer of fluid to or from the safety syringe(400) while also preventing inadvertent activation of a safety syringe needle retraction mechanism.
