Abstract

A connector for connecting an assembly to a pipe, which is highly leakproof with respect to the medium to be transported and is secure against separation under axial load. The connector comprises two materials A and B which swell to different degrees. A part comprising the more strongly swelling material A has, at the junction with the material B, a peripheral connecting lip which is substantially enclosed by the less swelling material B, so that a positive connection is achieved.
