Abstract
A syringe includes a syringe body that includes a stopper having an elastically deformable inner wall and delimiting a cavity. A piston is mounted so as to be able to slide inside the syringe body in an injection direction. The piston includes a rod. A pusher is arranged at a first end of the rod. A snap-fastening head is arranged at a second end of the rod and is snap-fastened inside the cavity of the stopper. The snap-fastening head has a planar bearing surface bearing against the inner wall of the stopper when the piston slides in the direction opposite to the injection direction. The snap-fastening head includes at least one protruding element that protrudes from the planar bearing surface and that is arranged to penetrate the inner wall of the stopper when the piston slides in the direction opposite to the injection direction.
