The invention relates to a safety device for a syringe for avoiding stab wounds, said syringe having a syringe body and a piercing means arranged on the distal end of the syringe body. The safety device comprises a sleeve element that extends along an axial direction (X) and at least partially encloses the piercing means and the syringe body, and an inner element which is at least arranged at least in sections inside the sleeve element and surrounds the piercing means. Said safety device is characterised in that the inner element comprises a rim section and a piercing means protection section surrounding the piercing means. Said rim section can be arranged on a distal end of the syringe body, the safety device is secured to the syringe body, and the piercing means protection section can be removed from the rim section before using the syringe.
