Abstract

A suitably tubular shaped inner part is attachable at its one end to the second pipeline and at its other end carries a first surface, which by coaction with a second surface inside the outer part can limit a separating movement of the parts. A sealing device is arranged to prevent the medium in the pipeline from leaking between the parts. The sealing device comprises a first seal coming into action when the inner part of the surfaces is pressed towards the outer part at a given pressure in the medium. A second seal placed behind the first seal is arranged resiliently in the axial direction of the parts to accommodate momentary high pressure occurring in the medium and passing the first seal.
