It enters the inside of the fluid pipe connecting portion 111 along the guide inclined surface 125a provided in the pipe.

前記の流体パイプ接続部１１１の内部に進入する流体パイプ１６０の係止フランジ１６１がロッキング部材１２０のロッキング部１２５を通過するときは、各ロッキング片１２１の回動中心突起１２２を中心に各ロッキング片１２１のロッキング部１２５側が外側に広がりながら各ロッキング片１２１の弾性支持片１２６側が内側に狭まるようになる。   When the locking flange 161 of the fluid pipe 160 entering the fluid pipe connecting portion 111 passes through the locking portion 125 of the locking member 120, each locking piece is centered on the rotation center protrusion 122 of each locking piece 121. The elastic support piece 126 side of each locking piece 121 narrows inward while the locking portion 125 side of 121 spreads outward.

そして、流体パイプ１６０の係止フランジ１６１がロッキング部１２５を通過すると、圧縮していた弾性支持片１２６が伸張しながら各ロッキング片１２１が元の位置に復帰するようになり、各ロッキング片１２１のロッキング部１２５の後端に設けられたロッキング突起１２５ｂが流体パイプ１６０の係止フランジ１６１に係止されて流体パイプ１６０をロッキングするようになる。   Then, when the locking flange 161 of the fluid pipe 160 passes through the locking portion 125, each of the locking pieces 121 returns to its original position while the compressed elastic support piece 126 expands, The locking protrusion 125b provided at the rear end of the locking portion 125 is locked to the locking flange 161 of the fluid pipe 160 to lock the fluid pipe 160.

一方、ハウジング１１０の流体パイプ接続部１１１にロッキングされた流体パイプ１６０を分離するときは、各ロッキング片１２１の弾性支持片１２６側を押すと、各ロッキング片１２１の回動中心突起１２２を中心に各ロッキング片１２１の弾性支持片１２６側が狭まりながら各ロッキング片１２１のロッキング部１２５側が外側に広がるので、流体パイプ１６０を外部に引き出せるようになる。   On the other hand, when the fluid pipe 160 locked to the fluid pipe connection portion 111 of the housing 110 is separated, when the elastic support piece 126 side of each locking piece 121 is pushed, the rotation center protrusion 122 of each locking piece 121 is centered. Since the elastic support piece 126 side of each locking piece 121 is narrowed, the locking portion 125 side of each locking piece 121 spreads outward, so that the fluid pipe 160 can be pulled out.
