First, when the handle support rod 23 is rotated to a predetermined angle or less, as shown in FIG. 5 (a), only the holder ring operating bar 42 moves forward while the holder ring 4 is moved to the left. As shown in Fig. 3, the tightening jaw 3 becomes loose and the pipe 1A is free. Thereafter, when the handle support rod 23 is further rotated by a predetermined angle or more, the pin 29 formed at the end of the handle support rod 23 along the long hole 32 as shown in FIG. While moving forward, the connecting rod 30 is advanced and thereby moved to the left until the pipe fixing ring 10. As a result, the pipe 1A tightly fixed by the fixing jaw 14 is completely separated from the socket 2.

When the pipe 1A is completely separated from the socket 2 as described above, the jaw actuating bar 25 is released freely. At this time, the wire rod 18a is returned to its original state by the restoring force of the spring 52. (14) also moves in the direction away from the outer surface of the pipe 1A so that the said pipe 1A can be taken out in the inside of the socket 2. As shown in FIG.                     

On the contrary, in order to fix the pipe 1A inside the socket 2, push the pipe 1A toward the socket 2 and pull the jaw operating bar 25 toward the handle 24 to fix the pipe 1A. 14 is in close contact with the outer surface of the pipe 1A, and in this state, a force is applied to the handle 24 to rotate the handle supporting rod 23 in the opposite direction to the above.

As a result, the pipe fixing ring 10 and the holder ring 4 are connected in the right direction by the connecting rod 30 and the holder ring operating bar 42 connected to the handle supporting rod 23. Is moved, whereby the tightening jaw 3 is tightened so that the pipe 1A can be firmly fitted into the socket 2 and fixed.
