PROBLEM TO BE SOLVED: To provide an insertion coupling easy in an intentional connection releasing. SOLUTION: When a sleeve 5 and a blocking device 6 are moved and separated, an inclined surface 21 is pressed to the front side edge of a hole to receive a hook 20 in such a manner as to move in the axial direction, and the hook 20 bears more solidly on a suppressor rib 2. When the blocking device 6 and a fluid conduit 1 are separated, the inclined surface 23 inside the hook is pressed to a suppresser rib 2, and when the blocking device is in the releasing condition that the inclined surface at the outer side of the hook is not pressed to the front surface edge of each hole, a holding arm is expanded, and the connection is released. The blocking device 6 has also an elastic releasing arm 19, and a part 29 at one outer side of the releasing arm 19 passes the hole 13 and projects in such a manner as to move in the axial direction. In order to remove simply, the movement in the axial direction of the blocking device to a releasing condition is generated by pressing together with the part 29 at the outer side of the releasing arm 19 in the radial direction passing through the inclined surface 33. |
