<p>The coupling (1) is between a first body (5) with a hole and a cylindrical end zone of a second body (1) by means of lips (8), which by positioning of the end zone over the surface causes scraping to occur, so that backward movement is prevented. The lips form part of an interrupted ring (3) and are the windings of a spiral (7). They are inclined in the application direction. The end zone during application can be displaced along the spiral during the elastic deformation of the ring. Additional pressure forces occur between the lips and the end zone when a force is exerted opposite to the application direction between the ring and the second body, so that by rotation of the second body in relation to the first body the spiral is affected, so that an axial movement always occurs and the end zone can be removed from the first body.</p> |
