The socket 3 is in a cylindrical shape having a protruding part 30 fitted to the lock groove 10 of the nipple 1. The hose 5 is of vulcanized rubber. The adhesive agent layer 7, being a unhardened film layer 6 with a transition temperature of glass higher than the normal temperature, is held between the nipple 1 and a wall of the hose 5, heated and hardened after the hose 5 is inserted. As a result, a sealing quality is improved by surely attaching by adhesion the internal peripheral surface of the hose wall to the peripheral surface of the nipple.
