Abstract: A quick-connect fitting for connecting a burner tube to a barbecue grill. The quick-connect includes a female connector and a male connector. In one embodiment, the female connector is attached to the burner tube and the male connector is connected upstream of the fuel supply. The female connector has an inwardly directed protrusion while the male connector has a corresponding longitudinal entry portion and circumferential groove. In the first step of assembly, the female connector is mated with the male connector by aligning the protrusion with the entry portion and urging the connectors together. In the second step of assembly, the female connector is rotated relative to the male connector such that the protrusion enters the groove to effectively prevent relative axial movement between the connectors.
