  • Patent number: 5492374
    Abstract: A separable insertion-type connection is provided for pipes. By way of an end piece having an exterior collar, a pipe can be sealingly inserted into an inserting opening of a connecting body which receives an elastic sealing ring as well as a supporting ring which, in the inserting direction, is arranged in front of the sealing ring and rests against the opening wall. The pipe can then be axially fixed in the inserting opening by a holding part which can be mounted on the connecting body. The insertion-type connection provides long service life of its sealing ring under extreme conditions. For this purpose, the supporting ring is equipped on its face which faces the sealing ring with a sealing lip which sealingly encloses the pipe end piece. As a result, it is achieved that, when acted upon by pressure, the sealing lip, independently of component tolerances, is pressed in a form-locking manner against the circumference of the pipe end piece.
