A syringe comprises a syringe body (2) with a cylindrical part (3), a piston body (5) with a piston (7), and a piston seal that limits a movement of the piston body in proximal direction with regard to the cylindrical part. The piston seal has been provided in such a way that this discemibly damages if the piston body is moved in proximal direction with regard to the syringe body. At least one stop section has been provided that protrudes outwardly in the radial direction on the piston body that is limited in the axial direction by at least one limiting section (27) of the piston seal that extends inwardly in the radial direction. The stop section that protrudes outwardly in the radial direction is formed through a stop cam (10) that is compressable inwardly in the radial direction, in which the limiting section has radial internal dimensions that are greater than the radial external dimensions of the piston and the radial internal dimensions of the cylindrical part, respectively.
