PROBLEM TO BE SOLVED: To improve a plug-in connector and avoid a collision against another surrounding structural member when the connector is fitted in a narrow space.SOLUTION: This invention relates a plug-in connector for a fluid conduit pipe in which, as a lock unit 12 for making a removable engagement under a coupling state having a coupling member 2 integrally engaged with a mating coupling member 4, a clamp-like holding supporter 14 resiliently deformable in a diametral direction is held outside the coupling member 2 under a state in which it outwardly encloses the coupling member in a peripheral direction at least partially. Under a state in which the holding supporter 14 sits on the coupling member 2, it may act mutually with the coupling member 2 through a fixing means 22. In this way, the holding supporter 14 can be selectively set to face different relative rotating position and at the same time it is fixed at each of the rotating positions by prohibiting a limitless free rotation around a plug-in axis X against the coupling member 2. |
