Abstract

The invention pertains to a piston-cylinder unit for a hinged lid, especially a motor vehicle hinged lid, with a closed first end, a cylinder, a piston installed in the cylinder with freedom to slide back and forth, the piston dividing the cylinder into a working chamber remote from the first end and a second working near the first end; and a piston rod, which is attached to one side of the piston, projects through the first working chamber, and passes out of the cylinder concentrically to the central longitudinal axis of the cylinder through a guide and sealing device at the second end opposite the first end, where a first locking element is provided on the piston rod, and a second locking element is provided on the cylinder to establish a mechanical interlock, and where one of the locking elements comprises a sleeve, which cooperates with the other locking element to establish an interlock.
