A needle protection device (2) for a vial (16) has a collar (4) at the base of which a number of finger grippers (6) extend. The collar (4) is placed about the hub (10) of a vial (16), and pushed there along until the gripper fingers (6) snap over the bottom surface of the needle hub (10) so as to fixedly couple the collar (4) to the needle hub (10) of the vial (16). Flexibly extending from the collar (4) is a housing (6) that is pivotable to a position in alignment along the longitudinal axis of the vial (16) for enveloping the needle (12), to thereby prevent the needle (12) from being exposed to the environment. A hook (18) integrated to the inside of the housing (6) ensures that the needle (12), the housing (6) could no longer move relative to each other once the hook (18) snaps over, and traps the needle (18), as the housing (6) is pivoted to its alignment position.
