Abstract
An insertion indicator for a metal quick connector assembly includes an annular base adapted to be releasably received within the mouth of a female connector component's axial bore, such that the male end form of the connector assembly's male component, including an external flange thereon, is insertable through the indicator's base into the axial bore. The indicator further includes two legs projecting both axially and radially-inwardly from its base so as to extend deeper within the female component's axial bore than the "locking" abutment surfaces of a retainer, also disposed within the bore, when the indicator is releasably received therein. Each leg is resiliently radially yieldable so as to permit passage of an external flange or upset bead on the male component through the indicator, whereupon the free end of each leg rebounds to provide an axially-disposed surface with which the indicator may thereafter be operatively ejected through engagement with the male component's upset bead upon slight retraction of the male component from within the bore.
