PURPOSE: To make the check of connection easy enough, extending the range of application, and further to make the check of slipout or fallout from the outside yet easier by means of an elastic claw wall and a check member or an easy-to-see positional relationship of a projecting wall even in a narrow, complicated connective place. CONSTITUTION: A seal ring member 6 and a bush member 7 both are installed in a small diametral chamber 3' part of a connector 1 piercingly installed with this diametrally expanded small diametral chamber 3' and a large diametral chamber 3 ranging to a flow hole 4 in the inner part of a shaft center. In addition, plural pieces of elastic claw walls 5 being surrounded by an almost U-shaped notch part 5' along the circumferential surface direction and energized inward aslant, is installed in a peripheral wall 1' part of the large diametral chamber 3', while in time of connecting a pipeline P, a bottom surface interposed in a gap part 9 with a side face of the notch part 5' being opposed to a free tip part of the claw wall is slipped or dropped out with contactual engagement to an annular bulge wall P' at the piping side, while this bulge wall is resiliently engaged and pressed with the sidepiece at the vicinity of a tip of the claw wall 5. |
