<p>PURPOSE:To secure an effective cross section and make a one-touch installation performable by making an engaged body be pressed outward aslant in the rear against an energizing means between a regulating ring and a long hole by a plug taper if a plug is inserted into a socket, and dropping the engaged body in an engaged recess after it is inserted as far as the specified distance. CONSTITUTION:When an end connection 36 of a plug 30 is inserted into an inserting port of a socket 35, an engaged body 56 is pressed to a taper part 40 of the end connection 36 against an energizing means 62 and moved aslant in the rear inside a long hole 55. When the plug 30 is inserted as far as the specified distance, a space, where the engaged body 56 is passable, is formed between an inner surface projecting peripheral part 59 of a regulating ring 58 and an outer circumferential surface of the end connection, whereby the engaged body 56 is pushed back by the energizing means 62, and it is dropped in a space between an engaged recess 51 and the regulating ring projecting peripheral part 59, so that the plug 30 is installed in the socket 35 in a one-touch manner. To remove the plug 30, the regulating ring 58 is pressed in whereby regulation of the engaged body 56 due to the projecting peripheral part 59 is released. With this constitution, a passage cross section is widely securable.</p> |
