PROBLEM TO BE SOLVED: To provide a quick coupling connector for precluding the sudden disconnection of a male member from a female member with the pressure of a fluid flowing in a pipe when one pipe is disconnected from the other pipe. SOLUTION: In a quick coupling connector for connecting pipes 4, 14 in a disconnectable manner, when bushes 10, 11 are first moved to the axial direction, the opening of a locking ring 9 with a pawl 9a is controlled and a safety ring 8 similarly with a pawl 8a is thereby located at a middle of stationing a male member B in the axial direction, making it possible to reduce pressure in the pipe 4 cooperating with the male member B. The male member B is finally released from a female member A when the bushes 10, 11 are then moved to the axial direction opposite to the previous direction. |
