Abstract

There is disclosed an injection syringe assembly comprising a cannula module including a two-part cannula shield device having a separate front cap, as well as a latched-in cannula holder in which a cannula is glued. In the mounted state, a plug-like cannula seal is received in the front cap and the cannula holding means is located forwardly of the syringe cone of a syringe body of an injection syringe. It is indirectly fastened to the syringe cone by aid of an elongated fastening portion of the cannula shield device. The cannula shield device includes two predetermined breaking points in order to be able to recognize immediately unauthorized manipulations at the syringe.
