Safety device for a syringe

A safety device for avoiding stab wounds for a syringe having a syringe body and a piercing means arranged at the distal end of the syringe body, the safety device comprising a sleeve element, which extends along an axial direction (X) and at least partially encloses the piercing means and the syringe body, and a collar element, which is arranged on a distal end region of the syringe body and locks the safety device in the axial direction (X), the collar element comprising at least one guide projection, which is guided in at least one guide track of the sleeve element, substantially in the axial direction (X), when the syringe body is moved relative to the sleeve element, wherein:

• 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 the movement of the syringe body relative to the sleeve element causing the collar element to rotate in the circumferential direction (U) on account of the guidance of the guide projection in the at least one guide track of the sleeve element, and
• wherein the collar element comprises three tolerance compensating elements, the tolerance compensating elements being arranged on the distal end of the collar element such that two central axes of the tolerance compensating elements in each case enclose an angle (α, β, γ).
