Abstract: A quick connector includes a retainer for detachably engaging male and female components of the quick connector together. The retainer includes an annular base with a recess mountable over a radially enlarged flange on the male component and circumferentially spaced legs extending axially from the base. An aperture in each leg engages a projection on the female component to interconnect the male and female components together. First and second seal members, each having the same inner diameter, but different outer diameters are pre-mounted on the male component and simultaneously engage different diameter portions of a stepped bore in the female component upon insertion of the male component into the female component.
