When the small diameter pipe 2 is pushed into the large diameter pipe 1 without pressing the curved portion 6 of the spring member 4 in connection with the pipe 2,
The inclined portion 8 is pushed by the tip of the large-diameter pipe 1, and the inclined portion 8 slides in the tip of the large-diameter pipe 1 and is retracted into the small-diameter pipe 2, whereby the engaging projection 7 and the curved portion 6 are formed. Is immersed in the small diameter pipe 2, and the large diameter pipe 1 and the small diameter pipe 2
It enables connection with (Fig. 7). Even in the case of separation, the large-diameter pipe 1 is further pushed into the small-diameter pipe 2 without pressing the curved portion 6, so that the inclined portion 8 is pushed at the end of the engagement hole 9 of the large-diameter pipe 1. As a result, the inclined portion 8 slides into the small-diameter pipe 2 while sliding on the end portion of the engagement hole 9, whereby the engagement projection 7 is disengaged from the engagement hole 9,
The large-diameter pipe 1 and the small-diameter pipe 2 can be separated (FIG. 8), and in this state, the small-diameter pipe 2 is rotated with respect to the large-diameter pipe 1 to shift the positions of the engagement hole 9 and the long groove 3, and then the large-diameter pipe 1 By pulling out the small diameter pipe 2 from the pipe 1, the large diameter pipe 1 and the small diameter pipe 2 can be separated. In this way, the large diameter pipe 1 and the small diameter pipe 2 can be connected / disconnected with one touch.
