A piston-cylinder unit includes a piston rod guided axially in a cylinder, a support disk fixed to the piston rod, a mounting element fixed to the support disk, and a protective sleeve which can be threaded over the mounting element. The protective sleeve has an end wall with an aperture profiled to receive the mounting element therethrough as the protective sleeve is fitted to the support disk, the protective sleeve being rotatable relative to the mounting element when fitted to the support disk, the mounting element having an axial support surface which can be positioned axially above the end wall to retain the protective sleeve.
