摘要： A quick connector including: (a) a tubular male element having an introduced end portion which has an extreme end portion and an annular protrusion portion; and (b) a tubular female element having a first receiving portion and a second receiving portion which have respective tubular shapes configured to receive therein the annular protrusion portion and the extreme end portion of the introduced end portion of the tubular male element, respectively. The first receiving portion has an elastically-deformable tongue portion which is defined by a U-shaped slot formed through the cylindrical wall of the first receiving portion. The tongue portion extends in a circumferential direction of the tubular female element, and has a free end portion which is displaceable in a radial direction of the tubular female member. An engaging protrusion portion is provided in the free end portion so as to protrude inwardly in the radial direction so as to be brought into engagement with the annular protrusion portion of the introduced end portion of the tubular male element in a snap action manner. The engaging protrusion portion preferably has a tapered guide surface in its inner surface.

摘要： When a retainer is mounted on or in a retainer mounting portion and is positioned at an inserting position, a pipe is inserted into the retainer mounting portion. An annular engaging projection of the pipe advances in the connector housing while spreading leg portions of the retainer outwardly. When the annular engaging projection reaches a connecting position, the retainer is automatically moved to an engaging position and snap-engages with the annular engaging projection.

摘要： A quick connector is configured as such that one axial end of an engagement window is co-planar with an annular end surface inside of a retainer holding portion. A checker jut toward an axial direction is provided integrally on a base portion of an inwardly directed engagement portion of a checker. The checker is mounted on the connector housing so that the checker jut toward one axial direction abuts the one axial end of the engagement window.
