ABSTRACT:
A quick connect connector for fast connection of fluid carrying assemblies such as a mating tube and a fluid unit. The connector includes a connector body which houses the connector components and accepts a redundant clip which pushes an upset bead of the male tube toward an annular seal which surrounds the end of the male tube. The redundant clip includes fingers which are received within an external groove on the connector body when the tube head is in the fully locked position within the housing. The fingers of the redundant clip proved a secondary locking feature in the event that the locking fingers of a primary locking within the connector body should fail. The position of the redundant clip provides a visual indication of a positive lock of the connector. The forward end of the annular seal within the connector body includes a unidirectional shut-off valve of duckbill seal which precludes outflow from the connector in the event of unintended or accidental disconnection of the mating tube from the connector.
