PROBLEM TO BE SOLVED: To perform a piping work in a restricted area easily by locking a sharp edge part located at the rear end of the base part of a socket member crimpingly into a stepped part which is provided in a large diameter chamber on the connector main body side. SOLUTION: A resin connector main body 1 is provided with a connecting cylinder wall 2 connected to a rubber hose at its top end side, a stepped small diameter chamber 3' and a stepped large diameter chamber 3 are interconnected in order to its circulating hole 4, and a stepped part is provided at the rear of the internal surfaces which form the large diameter chamber 3. Also an elastic seal ring member 6 is fitted closely to the small diameter chamber 3, and an annular bush member 7 for positioning is installed internally at the rear side of it. Then a socket member 5 comprising a thin wall metal elastic material is locked crimpingly on a stepped part in which a sharp edge part 5"' of which base part 5" is formed roughly in annual shape and of which inner side of its rear end is formed in a tapered surface expanding toward the rear is provided in a large diameter chamber 3. When a pipe P is connected, a claw wall 5' at the top end of it is locked to the annular dwelling wall P' of the pipe P for the connection of it. |
