9. The quick connect coupling of claim 8 , wherein the longitudinal portion of the housing includes a plurality of openings, and the sleeve includes a plurality of tabs.

10. The quick connect coupling of claim 9 , wherein the longitudinal portion of the housing includes at least three openings that are circumferentially spaced around the outer surface of the longitudinal portion of the housing, and the sleeve includes at least three tabs that are circumferentially spaced around the outer surface of the sleeve.

11. The quick connect coupling of claim 8 , wherein the sleeve includes a slot extending from the outer surface through the inner surface at the second end.

12. The quick connect coupling of claim 11 , wherein the sleeve includes a plurality of slots.

13. The quick connect coupling of claim 12 , wherein the sleeve includes two slots that are diametrically opposed to each other.

14. The quick connect coupling of claim 8 , wherein the opening in the longitudinal portion of the housing is generally D-shaped.

15. A quick connect coupling, comprising:

a housing including a longitudinal portion and a transverse portion, the housing having a longitudinal bore extending therethrough, the longitudinal portion having an outer surface and an inner surface, the longitudinal portion including an opening extending from the outer surface through the inner surface, 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

a sleeve operable to be inserted into the longitudinal bore in the housing, the sleeve being generally cylindrical shaped, the sleeve including a first end and a second end, the sleeve having an opening in each of the first end and the second end, an outer diameter of the second end of the sleeve being greater than an outer diameter of the first end of the sleeve, the sleeve having an outer surface and an inner surface, the sleeve including a slot extending from the outer surface through the inner surface at the second end, the slot including a first end and a second end, the second end of the slot extending to the second end of the sleeve, the second end of the slot being open, the sleeve including a tab extending outwardly from the outer surface near the second end, the tab being operable to extend into the opening in the longitudinal portion of the housing.
