<p>PURPOSE:To facilitate a pipe insertion completing judgment by forming three large, medium and small diametral holes in a body after connecting them with each level difference part, installing a sprung sleeve in the medium diametral hole and also a means for engaging the tip of a flexible pipe with this sleeve, and setting up a piece of packing, sticking fast to a pipe circumference, in the large diametral part. CONSTITUTION:A flexible pipe 9 (hereinafter referred merely to as a pipe) made up of cutting off a protecting pipe 10 into constant length is inserted into from the side of a nut 2, and a tip crest part 9b is made contact with an incline 3a, thrusting it therein further. With this, a ring spring 4 moves to the right together with the sleeve 3. Then the ring spring 4 is engaged with a small diametral level different part 1d and its movement is checked, but the sleeve alone continues going to the right. Therefore, the ring spring 4 is released and made diametrally contractible by dint of its spring force. With the pipe 9 thrusted in, if the ring spring 4 and a root part 9c of the pipe 9 are matched with each other, it is engaged with this root part 9c with a click, thus connection is completed and recognized.</p> |
