PROBLEM TO BE SOLVED: To couple a pipe to another pipe without a clip. SOLUTION: A joint portion 2 of elastic material is formed on an outer periphery of an intermediate joint body 1 of a resin member by double molding so as to constitute a pipe joint section 4. The joint portion 2 is provided with a falling-out prevention rib 21 and leakage prevention ribs 22a, 22b at its top end portion 13. When the pipe joint section 4 is inserted into the pipe 3, the falling-out prevention rib abuts against a projected line part 31 for falling-out prevention which is formed on the pipe 3 in a radially inwardly extending manner and a pipe opening end 32 is engaged with an engagement projected line part 11 of the intermediate joint body, so that the pipe joint section 4 is prevented from falling out from the pipe 3. It is also possible to prevent leakage due to contact between the leakage prevention ribs and a pipe internal surface 33. COPYRIGHT: (C)2007,JPO&INPIT
