ABSTRACT:
A composite syringe has an injector body and a cylindrical protector which covers a cylinder of the injector body. The protector includes a sleeve separably connected to a base which is secured to an outer periphery of the cylinder's forward end. The sleeve, when separated from the base, is caused to slide towards the cylinder's end and beyond a tip holding a needle, until it engages again with the base at a position where the needle is covered entirely with the sleeve. This prevents any accident of erroneous pricking or puncture of a user of the syringe or other people coming into contact with the syringe.
