Abstract

A branch pipe part is provided with a collar and a downwardly extending skirt, the free end of the branch pipe part comprising a first outwardly extending projection and the lower portion of said pipe part being provided with longitudinal incisions allowing deformation of said lower portion. The outer wall of the space formed by collar and skirt may have apertures for passing a lip of a sealing member. In order to avoid further deformation of the lower portion with incisions after connection with a main conduit, a deformation-preventing bush is pushed into the lower portion and locked by means of a cam. For decreasing the distance between the outer side of a main conduit connected with the branch pipe part, the skirt may be provided with a removable adapting ring, an intermediate part thereof decreasing the distance between the outer side of the main conduit and the free lower end of the skirt. The lower free end or the bottom side of the intermediate part and the outer side of the main conduit tightly engage a part of the sealing member, said sealing member comprising four legs.
