Quick connector with snap-on frangible retainer

摘要

A retainer for releasably locking the male and female components of a quick connector. The retainer is releasably insertible into a transverse bore in the female component and is blocked from full insertion by a projection. An extension projects from the retainer and has an aperture sized to receive the tip end of the male component, but not a radial flange on the male component when the retainer is partially inserted into the female component. Forced insertion of the male component breaks off a ring portion of the extension thereby enabling the radial flange on the male component to fully move into the female component. The retainer can then be urged into the fully latched position locking the male and female components. Lock projections on the retainer engage grooves in the bore in the female component to releasably lock the retainer in a partially inserted, shipping position in the female component and engage exterior lock surfaces on the housing on full insertion of the retainer to lock the retainer to the female component.
