PROBLEM TO BE SOLVED: To provide a high-reliable quick connector not to separate a lock member from a female member only by pressing the operation arm part of the lock member and to perform mounting and demounting between the lock member and the female member by applying other operation. SOLUTION: In a quick connector to couple a male member 30 to a cylindrical female member 10 provided at the other end with a hose insertion part through a lock member 20 held at a containing chamber 11a at one end, by pressing the operation arm part 23 of the lock member 20, a second lock part 22 is radially internally deformed. Through rotation operation in a peripheral direction of an operation arm part 23, the mating protrusion 24 of the second lock part 22 of the lock member 20 is registered with the mating groove 15 of the first lock part 13a of the female member 10. This constitution performs mounting and demounting between the female member 10 and the lock member 20. |
