A piston-cylinder unit, in particular a shock absorber, which comprises a cylinder tube in which a piston rod is located so that the piston rod can move axially, is disclosed. The piston rod is guided by a piston rod guide with a seal which closes the cylinder tube, whereby a closing tool beads an edge which projects beyond the piston rod guide. The cylinder tube has an edge in the shape of a truncated cone, which edge encircles the piston rod guide, and which edge is divided into individual truncated cone surfaces by means of partial closing surfaces.
