The invention provides a medical injection needle safety device (8) comprising a protective cover (19) pivotally connected to a carrier (18) configured to be directly or indirectly secured to a needle hub having a needle tip projecting therefrom. The protective cover (19) is configured to move from a pre-use initial protective position to an in-use non-protective position and then to a post-use final protective position. After completion of the injection, the protective cover (19) pivots inward until the locking mechanism engages the needle (11) in the final protective position and the protective cover (19) maintains an offset angle with respect to the longitudinal axis of the syringe (10). A locking member (80, 81) is disposed adjacent to the profiled flanks (66, 67) of the lugs (60) when the protective cover (19) is in a pre-use initial protective position. The locking member (80, 81) and the profiled flanks (66, 67) comprise mating drive surfaces that engage the locking member and elastically deform the locking member (80, 81) in an outward transverse direction with respect to a longitudinal axis of the protective cover (19) when the protective cover (19) is moved inwardly to a post-use final protection position. When the protective cover (19) is in use, the drive surface is disengaged, allowing the locking member (80, 81) to elastically return inward to an undeformed state so as to be disposed adjacent to the inner blocking surface (63) of the lug (60), locking the protective cover (19) in a post-use final protective position. A return movement or force will cause the locking member (80, 81) to be further pushed below the inner blocking surface (63).
