In order that the bite-type fitting pipe joints can also be installed in connecting bodies which are provided with an inside taper inclined at any angle, it is proposed according to the invention that an adapter cone be inserted whose inside tapered hole has the amount of taper required for the cutting-in of the packing ring and whose outside taper circumference is slightly smaller than the existing inside taper of the connecting piece, whereby the adapter cone has a recess on its free front end near the necessary pipe stop that forms a collar-shaped shoulder whose outer surface forms the extension of the outside taper. This shoulder is flexibly and elastically deformed during creation of the pipe joints by interaction between the pressure piece and the connecting piece to form a local narrow sealing surface with the inside taper of the connecting piece.
