PROBLEM TO BE SOLVED: To facilitate insertion of a retainer member, prevent infiltration of dust, or rainwater and car washing water into the interior of a connector body, to stabilize an engaging pressure at a claw wall part, and eliminate a fear of leakage occurring of a long period and effect reliable connection. SOLUTION: A seal ring member 6 and a bush member 7 are internally arranged at the small chamber part of a connector body 1 formed such that a small chamber 3' and a large chamber 3 are extended through an axis. A retainer member 5 having an elastic claw wall 5' having an annular base part fixed at a stepped part in the vicinity of a rear end part and energized in a state to incline opposite to the internal part of a front is arranged at the internal part of the large chamber. A release member 8 from which a guide wall 8' is protruded is movably arranged at an opposite portion at the rear part of a retainer member 5. Further, a cap member 9 formed of a resilient material is formed by arranging an engaging means 11 bracing a release member 8 and engageable with the peripheral surface of a connector body at a cylinder wall part, and covering with the cap member is effected. During a connection state of a piping P, an annular expansion wall P' in the vicinity of the connection end part of the piping P is engaged with the claw wall with a pressure for connection. |
