ABSTRACT:
A quick connector includes a first member, a second member, an engager claw member and an urging member. The first member includes a first tube and a ring-shaped projection. The second member includes a socket at an end thereof, the socket including a tapered regulatory inner peripheral surface. The engager claw member is made movable in an axial direction of the socket, disposed in the second member, and includes a ring-shaped base, a plurality of arms being deformable in a radial direction and a claw extending from an end of the arms and engaging with the ring-shaped projection of the first member. The urging member presses the engager claw member onto the tapered regulatory inner peripheral surface of the socket, and urges the claw inwardly in a radial direction. Thus, in the quick connector, enhanced engagement can be achieved between the claw of the engager claw member and the ring-shaped projection of the first member, thereby securely preventing the first member and the second member from relatively moving in a direction being perpendicular to an axial direction and in an axial direction.
