Abstract: An insertion indication device for use with a quick connect fitting includes a generally annular base member which is adapted for positioning about a male conduit inside of a connector housing. One or more leg members extend axially from the base member and terminate near an axial opening formed in the housing for receiving the conduit. A generally annular indicator member positioned adjacent to the opening releassably engages the end members. Upon couplings of the male and female elements of the quick connector, the indicator member is separated from the leg members to provide visual conformation that coupling has taken place.

Abstract: An insertion indicator employed in conjunction with a quick connector assembly includes a base member carried within a female housing, two or more leg members extending axially from the base member and terminating adjacent an axial housing opening. A generally annular indicator member is disposed substantially within the housing opening and releasably engages the ends of the leg members. Means are provided to axially displace the base member upon engagement of the male and female elements to effect separation of the base and indicator members. Guide and limiting means are provided to ensure proper orientation of the indicator device relative to the quick connector before and during coupling of the male and female elements.

Abstract: An insertion indicator device (10) is employed in conjunction with a quick connector (12) assembly comprising a male element (14) and a female element (16). The indicator device includes a base member (112) carried within the female element. Two or more leg members (114, 116) extend axially from the base member and terminate adjacent an axial housing opening. A generally annular indicator member is disposed substantially adjacent the opening and releasably engages the ends of the leg members. Means are provided to axially displace the base member upon engagement of the male and female elements to effect separation of the base and indicator members. Lastly, guide means are provided to ensure the maintenance of proper orientation of the indicator device with respect to the quick connector before and during the engagement process.

Abstract: A quick connector for connecting fluid lines includes a first connector having a housing for receiving a tube carrying spool. The spool sealingly engages an endform on the tube to form a metal-to-metal seal. A retainer in the form of ring having a plurality of angularly and radially extending, resilient legs extending therefrom and terminating in end pads is mountable in the housing in engagement with the spool with the end pads disposed in an annular, inward facing channel in the housing. A pop top is slidable along the tube to bias the retainer legs radially inward to allow insertion of the retainer into the bore in the housing and then is removed to allow the legs to snap radially outward bringing the end pads into engagement with housing channel. An assurance clip is mountable interiorly between the legs of the retainer and the spool to maintain the retainer legs in a radially outward position in engagement with the channel in the housing.

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.
