A quick connector includes a female pipe having a flange in the outer peripheral part thereof, a male pipe having a retainer mounting part, and a retainer slidably mounted on the retainer mounting part of the male pipe to slide at a right angle to the axial direction of the male pipe, in which the female pipe and the male pipe are connected with each other by the retainer holding the flange of the female pipe, and the retainer is allowed to move from a temporarily fixed position to a completely pushed-in position on the retainer mounting part only when the female pipe and the male pipe are in a completely connected state, so that a worker can easily and reliably check whether the pipes are in an incompletely connected state or in a completely connected state by means of hand feeling only without relying on a visual check.

What is claimed is: 1. A quick connector comprising: a female pipe having a flange on an outer peripheral part thereof; a male pipe having a retainer mounting part defining sliding grooves and fixing grooves; and a U-shaped retainer slidably mounted on the retainer mounting part of the male pipe to slide at a right angle to the axial direction of the male pipe; wherein the female pipe and the male pipe are connected with each other by the retainer which holds the flange of the female pipe; and wherein the retainer is allowed to move from a temporarily fixed position in which the retainer is mounted in the sliding and fixing grooves, to a completely pushed-in position on the retainer mounting part only when the female pipe and the male pipe are in a completely connected state. 2. The quick connector according to claim 1, wherein the retainer mounting part has a protrusion piece for preventing the retainer from moving backward, so that the retainer in the temporarily fixed position is movable only toward the completely pushed-in position when the female pipe and the male pipe are in the completely connected state.
