QUICK CONNECTOR

摘要

To provide a quick connector capable of surely confirming that a pipe body is engaged by a retainer when an elastically-deformable claw of the retainer and an elastically-deformable claw of a checker are adjacently arranged in an axial direction. Checker-axis direction elastically-deformable claws 52 and 52 have distal-end sides formed flexibly deformable in the axial direction, maintain a state of being engaged by a second engagement portion 46 of a retainer body 42 by having deflective deformation regulated by a retainer diameter-expanding elastically-deformable claw 49 in a state in which the retainer diameter-expanding elastically-deformable claw 49 is expanded diametrically, and regulate sliding from a first position with respect to the retainer body 42 toward a set radial direction by being engaged by the second engagement portion 46 of the retainer body 42. The checker-axis direction elastically-deformable claws 52 and 52 become releasable from engagement with the second engagement portion 46 of the retainer body 42 in a state in which the retainer diameter-expanding elastically-deformable claw 49 has restored its original shape, and thereby become slidable with respect to the retainer body 42 from the first position toward the second position in the set radial direction.
