Abstract
Protective tube for a piston-cylinder assembly of the type including a piston rod located with freedom of axial movement in a cylinder, the rod also having a section which extends outside the cylinder. A retaining element for the protective tube is attached to the piston rod, which retaining element includes a multi-part connecting ring, the parts of which are installed in the radial direction toward the piston rod and are operatively connected to it. The protective tube is connected to the connecting ring parts so that these parts come together to form a connecting ring which is braced at least in the radial direction.

A piston cylinder assembly comprising
- a cylinder having an axis,
- a piston rod which is free to move axially in said cylinder and has a section extending outside the cylinder,
- a protective tube which is coaxial to said piston rod and said cylinder, and
- a retaining element which fixes said protective tube to said piston rod, said retaining element comprising a multi-part connecting ring comprising connecting parts which are fitted radially toward said piston rod and lie in a common plane which is orthogonal to the cylinder axis, said connecting ring being braced at least in the radial direction by the protective tube.
