An adjustment screw held on the inner tube is operatively connected to an internally threaded bore in the inner element A clamping section is arranged on the expanding element, which, in a relaxed state, has a greater radius than the radius of the expanding element. The clamping section is elastically offsettable inwards counter to a restoring force.
