SAFETY DEVICE FOR A SYRINGE

The invention relates to a safety device for avoiding stabbing injuries, for a syringe having a syringe body and a piercing means arranged on the distal end of said syringe body. The safety device comprises a sleeve element that extends in an axial direction (X) and encloses at least partly the piercing means and the syringe body, and a collar element that is arranged on a distal end region of the syringe body and locks the safety device in the axial direction (X), said collar element having at least one guide projection which is guided in at least one guide track of the sleeve element during a movement of the syringe body relative to the sleeve element substantially in the axial direction. The safety device is characterised in that the collar element is arranged on the distal end region of the syringe body so as to be rotatable in a circumferential direction (U) and has at least one tolerance compensating element which is in operative contact, mechanically, with the syringe body so that tolerances of the syringe body can be compensated for.
