Abstract
A pipe connector having excellent pressure tightness and including a female connector (), a male connector () and a retainer () is constructed so that the incomplete connection of the female connector () and the male connector () can be clearly perceived when the retainer is falsely locked. The retainer () has side walls (), first retaining lugs () formed on the inner side of the side walls (), respectively, each having a first end edge () that engages an annular ridge () formed on the male connector () to restrain the male connector () from axial backward movement when the retainer () is pushed into the female connector () with the male connector () completely inserted in the female connector (), and a second end edge () opposite to the first end edge (), and second retaining lugs () formed on the inner side of the side walls () and spaced at least a distance corresponding to the width of the annular ridge () apart from the first end edges () of the first retaining lugs (), respectively. The second retaining lugs () are in contact with a retaining member () fitted in a bore formed in the female connector () to prevent O rings () fitted in the bore of the female connector () from coming off the bore of the female connector () to restrain the retaining member () from axial movement.
