Abstract

Refinements introduced into joints to connect two plastic pipes comprising a first pipe section having an end part including an inner surface and an outer surface, a second pipe section having an end part including an inner surface and a surface outside, said end part of said second pipe section having an outside diameter slightly less than the inside diameter of the end part of said first pipe section, at least one helical groove formed in. a preselected one of said inner and outer surfaces of the end part of a preselected one of said pipe sections, and at least one helical rib integrally formed in and projecting from a different preselected one of said inner and outer surfaces of the end part of the other of said pipe sections, said preselected surfaces being selected and said helical groove and said helical rib being configured in such a way that said rib is intended to cooperate with said groove to connect said pipe sections to each other in a threaded form, characterized in that said preselected pipe section including said helical groove further includes a notch formed in the same preselected surface as said groove, which extends from a predetermined point in said groove towards the most forward end of the end part associated with said groove, said section pipe presel sectioned including said helical rib further includes a protruding hook portion located at a predetermined point along said rib and extending away from the leading end of the end portion associated with said rib, said hook portion and said notch to mate with each other after said tube sections have been threaded together to interlock said sections one with respect to. another, and a sealing gasket to automatically force said pipe sections longitudinally in the direction of moving away from each other after said sections have been threaded together, so as to make said notch and said hook part marry one another, said joint also providing a hermetic seal between said pipe sections.
