ABSTRACT:
A quick connect coupling including a female connector member adapted for quick connect engagement with a male connector member. The male connector member has an annular bead defined by leading and trailing annular edges. The female connector member defines an axial bore sized to slidably receive a leading end of the male member defined forwardly of the leading annular edge of the bead and a plurality of circumferentially spaced resilient fingers adapted to snap into position behind the bead and into engagement with the trailing annular edge of the bead as the leading end of the male member moves into the bore and the leading annular edge of the bead moves into engagement with a radial seating surface defined around the entrance to the bore. The intersection between the bore and the radial seating surface is relieved or chamfered over a radial distance less than the radial height of the bead so that the leading annular edge of the bead may seat against the radial seating surface, and the resilient fingers may snap into position behind the trailing annular edge of the bead, irrespective of tolerance variations in the contour of the leading annular edge of the bead caused, for example, by normal manufacturing tolerances or by tool die wear.
