の問題を有するものであった。(Problem to be Solved by the Invention) However, in such conventional technology, due to the structure of the cylindrical wall at the base of the socket body (23), the claw walls (23°, 23°”) are While reducing the diameter, the peripheral wall near the base of the claw wall is pressed from the rear of the diameter expanding chamber (22) so that it passes inside the hanging wall (21°) and engages the hanging wall (21°). The mounting operation is troublesome due to the sagging, deformation at the base, and the piping (P).
o) In connection with the snap action of the claw wall (23°, 23") during connection, the socket body (23) is generally large in size, which necessitates a large diameter of the entire product including the connector body (23). However, when used in a narrow space when installed, there is a problem that interference with other parts may occur, causing problems, and the claw walls (23', 23"') become long due to the large size. This has the problem of weakening the engagement force at the bulging wall (Pl'') on the piping (Po) side and causing fatigue, resulting in a lack of reliable connection over a long period of time.

In addition, the socket body itself can be made generally compact, making the entire product particularly compact in the radial direction, eliminating concerns about problems caused by interference in narrow spaces during installation, and making it easier to prevent piping from reaching the bulging wall. The object of the present invention is to propose a connector for connecting small-diameter pipes that can securely perform spring-like pressing and engagement and maintain a sufficient connection over a long period of time.

とができるのである。(Function) Since the present invention is configured as described above, the socket body has a C-shaped shape, and the distal end side has an annular wall that engages with the bulging wall portion on the piping side. Due to the structure of the socket body, which has a rearward opening claw wall that springs onto the hanging support wall of the connector body on the side, the socket body can be assembled in advance on the piping side for connection. The connection can be made by one-touch operation by pressing the socket, making the connection operation extremely simple, and the socket body itself can be made compact, making the overall product shape particularly compact in the radial direction. This eliminates the worry of problems such as interference in narrow spaces during installation, and the claw wall, which can be made relatively short, sufficiently absorbs the spring-like engagement force at the bulging wall of the pipe. This allows the connection to be maintained reliably over a long period of time.
