Abstract
A quick connect coupling for tubing. The coupling includes a tubular male connector member adapted to be telescopically received within a tubular female connector member. The female connector member includes a tubular housing and a tubular retainer cap which is permanently bonded to the housing utilizing a sonic welding technique and which defines prong portions for latching coaction with an annular bead on the male member. The coupling further includes a unitary elastomeric seal positioned in a bore of the female member housing and defining a series of axially spaced, radially inwardly extending seal ribs slidably and sealingly engaging the outer circumferential surface of the male connector member.
