<p>The invention relates to a coupling between a first body (5) with a hole, and a cylindrical end zone of a second body (1) by means of tongues (8) which, when said end zone is arranged, scrape over the surface thereof, whereby the backward movement is blocked. The coupling has the feature that the tongues form part of an interrupted ring (3); the tongues are the windings of a helix; the tongues are inclined in the direction of arrangement; the end zone can displace along the helix during arrangement with elastic deformation of the ring; additional pressure forces occur between the tongues and the end zone when a force in opposite direction to the insertion direction is exerted between the ring and the second body; whereby, when the second body rotates relative to the first body, the helix is followed so that an axial movement also occurs and the end zone of the first body can be removed.</p> |
