摘要

At least one force transmission component(8) is attached to at least one head piece(4) and extends in the direction of the other head piece(5) and passes through it with axial movement. The force transmission component runs co-axially to the contraction sleeve(3). An annular seal(24) in the form of a seal packing is provided on the head piece through which passes the force transmission component and encloses the latter with sealing contact.
