<p>PROBLEM TO BE SOLVED: To provide a rubber made branch pipe joint capable of using without slipping off a branch pipe and without necessitating a socket by providing a branch pipe joint with two stoppers on an inserting part while being disposed in nearly parallel with a circumference of a double pipe and being protruding in both outer directions of the diameter of the branch pipe joint. SOLUTION: A branch pipe joint 1 is used by inserting into a horizontal hole 21 disposed on a synthetic resin made double pipe 2. On its inserting part, two stoppers are disposed in nearly parallel with a circumference of the double pipe 2 and by protruding in both outer directions of a diameter on an outer periphery of the branch pipe joint 1. Since the branch pipe joint 1 is made of rubber, it can easily inserted into a horizontal hole 21 disposed on the double pipe 2 by folding in a small size. Simultaneously, two stoppers 11 disposed by protruding to the inserting part are fitted to a hole part 22 formed when the horizontal hole 21 is disposed on a crest part nearly crossing the double pipe 2, and sliding is prevented by fitting the two stoppers 11 to the hole part 22. It is thus possible to easily connect the branch pipe to the double pipe corresponding to a main pipe.</p> |
