Abstract
Piston-cylinder unit includes a piston rod guided with freedom of axial movement in a cylinder, where at least part of the piston rod is enclosed by a piston rod protector, which is designed with at least limited axial elasticity. At least one retaining surface of the piston rod protector enters into a positive connection with at least one stop surface on the cylinder side, and an auxiliary assembly bevel allows the piston rod protector to buckle over a certain stroke range of the piston rod during the installation of the protector, so that the retaining surface snap-locks onto the stop surface on the cylinder side.
