The sleeve has a slot(2) in the longitudinal direction in the region of this slot on both sides the sleeve consists of an elastomer which is harder than the other one. In these areas on the respective opposite lying sides of the slots there is at least one undercut recess(6) and an interacting barb(5) which may be hollow inside.
