1. 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, the transverse portion having a first side and a second side, the second side of the transverse portion of the housing having an internal surface, the housing including a lead out geometry, the lead out geometry extending from the internal surface of the second side of the transverse portion of the housing, the lead out geometry being integrally formed with the housing;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; andbias structure on at least one of the housing and the clip, the bias structure being operable to bias the clip from a position in which the bore in the housing and the opening in the clip are aligned toward a position in which the bore in the housing and the opening in the clip are not aligned;wherein the lead out geometry causes the second side of the base portion of the clip to move away from the internal surface of the second side of the transverse portion of the housing when the clip is moved from the position in which the bore in the housing and the opening in the clip are not aligned to the position in which the bore in the housing and the opening in the clip are aligned; andwherein the lead out geometry is 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. 2. The quick connect coupling of claim 1, wherein an action required to disconnect the coupling with the lead out geometry is the same as an action that would be required to disconnect the coupling without the lead out geometry. 3. The quick connect coupling of claim 1, wherein the lead out geometry includes a ridge on the housing. 4. The quick connect coupling of claim 3, wherein the ridge interacts with a groove in the clip. 5. The quick connect coupling of claim 4, wherein the ridge extends from the internal surface of the second side of the transverse portion of the housing, and the ridge is integrally formed with the housing; andwherein the groove extends into the second side of the base portion of the clip, and the groove does not extend through the first side of the base portion of the clip. 6. 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, the transverse portion having a first side and a second side, the second side of the transverse portion of the housing having an internal surface, the housing including a ridge, the ridge extending from the internal surface of the second side of the transverse portion of the housing, the ridge being integrally formed with the housing;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, the clip including a groove, the groove extending into the second side of the base portion of the clip, the groove not extending through the first side of the base portion of the clip; andbias structure on at least one of the housing and the clip, the bias structure being operable to bias the clip from a position in which the bore in the housing and the opening in the clip are aligned toward a position in which the bore in the housing and the opening in the clip are not aligned;wherein the ridge causes the second side of the base portion of the clip to move away from the internal surface of the second side of the transverse portion of the housing when the clip is moved from the position in which the bore in the housing and the opening in the clip are not aligned to the position in which the bore in the housing and the opening in the clip are aligned; andwherein the ridge on the housing interacts with the groove in the clip 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. 7. The quick connect coupling of claim 6, wherein an action required to disconnect the coupling with the ridge is the same as an action that would be required to disconnect the coupling without the ridge. 8. 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, the transverse portion having a first side and a second side, the second side of the transverse portion of the housing having an internal surface, the housing including a projection extending upwardly inside the transverse portion of the housing, the housing including a ridge, the ridge extending from the internal surface of the second side of the transverse portion of the housing, the ridge being integrally formed with the housing; anda 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, the clip including a groove extending into the second side of the base portion of the clip, the groove not extending through the first side of the base portion of the clip;wherein the clip interacts with the projection on the housing to bias the clip from a position in which the bore in the housing and the opening in the clip are aligned toward a position in which the bore in the housing and the opening in the clip are not aligned;wherein the ridge causes the second side of the base portion of the clip to move away from the internal surface of the second side of the transverse portion of the housing when the clip is moved from the position in which the bore in the housing and the opening in the clip are not aligned to the position in which the bore in the housing and the opening in the clip are aligned; andwherein the ridge on the housing interacts with the groove in the clip 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. 9. The quick connect coupling of claim 8, wherein an action required to disconnect the coupling with the ridge is the same as an action that would be required to disconnect the coupling without the ridge.
