Push-fit connector resisting tensile forces transmitted by polyolefin pipes, has securing rings with annular teeth including circumferentially-short, sharp projecting tips

摘要

Projecting teeth of the securing ring (12) are formed as surrounding ring-shaped ridges (17, 18, 19). At least one of them includes circumferentially-short, sharply-projecting tips (23) which are slightly raised with respect to the remainder of the ridge.
