ABSTRACT:
A tube or pipe connector of plastic for corrugated pipes or tubes is adapted to be folded open in the axial direction, comprises two half members connected via a film hinge and provided with a detent member for mutual locking of the half members, and at least one portion which is adapted to receive corrugated pipe and the interior of which is formed to match the outer periphery of the corrugated pipe. The pipe connector is provided with a tube piece which has a thread and a stop member is provided which has an outer diameter greater than the outer diameter of the tube piece. Furthermore, a tube connector of plastic is proposed for corrugated pipes of different outer diameter, and a divisible nut of plastic for such tube connectors serves for securing the threaded tube pieces.
