    • The pipe 1 includes in one end portion thereof a metal cap portion 2 on which an O-ring 5 can be mounted, and a connecting portion 6 in the other end portion. A delivery pipe 9 includes a communication hole having an undercut shape and an engaging recessed portion 21. A fixing clip 21 including a mounting portion 16 and a securing portion 17 having rigidity is mounted on the portion of the pipe 1 located just above the metal cap portion 2. The securing portion 17 includes a plurality of securing claws 18 so arranged as to surround the metal cap portion 2, and a rotation preventive projection 19. When the metal cap portion 2 is fitted into the communication hole 12, the securing claws 18 are secured to the upper hole portion 14 of the communication hole 12, and the rotation preventive projection 19 is engaged with the engaging recessed portion 21. The metal cap portion 2 is fixed in such a manner that the securing claws 18 surround at least the metal cap portion 2 and the securing portion 17 can be made relatively short. Due to this, the metal cap portion 2 itself can be fixed so strongly that it can be prevented from wobbling even a stress is applied to the pipe 1.
    • 管1的一端部具有能够安装有O形环5的金属盖部2和另一端部的连接部6。 输送管9包括具有底切形状的连通孔和接合凹部21.包括安装部分16和具有刚性的固定部分17的固定夹21安装在位于金属帽正上方的管1的部分上 固定部分17包括多个设置成围绕金属盖部分2的固定爪18和防旋转突起19.当金属盖部分2装配到连通孔12中时,固定爪18 被固定到连通孔12的上孔部分14,并且防转动突起19与接合凹部21接合。金属帽部2固定成使得固定爪18至少包围金属 盖部分2和固定部分17可以制成相对较短。 由此,金属盖部2本身可以如此牢固地固定,即使对管1施加应力,也可以防止其摆动。
