The synthetic resin body comprises a flow passage(111) and a first groove portion(115). A first groove portion is formed on the inner surface of a sealing member. The metal sleeve is coupled with the pipe elements and inserted into the synthetic resin body. The metal sleeve comprises a through hole(131) and a second groove portion(134). The through hole is connected to the flow passage of the synthetic resin body. The second groove is formed on the outer surface of a sealing member and engaged with the first groove portion. The fixing member is coupled with the synthetic resin body and fixes the resin body to the metal sleeve.
