<p>PROBLEM TO BE SOLVED: To provide a pipe joint which firmly connects a corrugated pipe and has a high leak prevention function preventing a liquid in the corrugated pipe from leaking even when a pressure rises in the connected corrugated pipe. SOLUTION: A pipe joint 1 has a shape such that fixing swollen parts 4, 4... are protrusively provided in an internal surface of a long scaled band-shaped part 3, flange parts 5, 5a are suspension-provided in both end edges of the band-shaped part 3, a tongue piece 9 is extendibly provided in an end edge in a side suspension-providing the flange part 5, and a recessed groove 10 is engraved in an inner side of the other end edge. The joint is used in a set of two joints so as to alternate a direction, the respective band-shaped parts 3, 3 are wound to a joint line of a corrugated pipe so as to fit the fixing swollen parts 4, 4... to a bottom groove, the tongue piece 9 is fitted to the recessed groove 10, further in a condition that fitting protrusions 7, 7... are fitted to fitting recessed parts 8, 8..., the fellow flange parts 5, 5a are screw mounted, so as to connect the corrugated pipe.</p> |
