Zusammenfassung:	The present invention is relates to a needle cover lock for an autoinjector (1) comprising a prefilled syringe (7) with a needle (9). If a device cap (20) is attached to the autoinjector (1) a deflection of a locking member (33) of the autoinjector is prevented by a stop surface (12) and by a blocking surface (27) of the cap (20) and thereby the cover sleeve (30) is prevented to exit an extended position. If the device cap (20) with its blocking surface (27) is removed from the autoinjector (1) the locking member (33) is allowed to deflect thereby allowing the needle cover sleeve (30) to exit the extended position and to move towards a retracted position. The locking member (33) is deflectable in a plane tangent to a circumferential outer surface of the cover sleeve (30) if the device cap (20) is removed.
