Patent ID: 8764068

Claim:
A quick connect coupling, comprising: a housing including a longitudinal portion and a transverse portion, the housing having a longitudinal bore extending therethrough, the transverse portion having a top side and a bottom side, the transverse portion having an opening extending from the top side through the bottom side transversely to the bore; a clip including a top portion and a base portion, the base portion having a first side and a second side, the base portion having a top side and a bottom side, the base portion having an opening extending from the first side through the second side between the top side and the bottom side, the top portion extending outwardly from the first side of the base portion near the top side of the base portion; bias structure on at least one of the housing and the clip, the bias structure being operable to bias the clip toward a position in which the bore in the housing and the opening in the clip are not aligned; and retention structure on at least one of the housing and the clip, the retention structure being operable to significantly increase the resistance to disconnect the coupling in a pressurized state, but not significantly increase the resistance to disconnect the coupling in an unpressurized state; wherein the retention structure is on the clip.
