A secure yet rotatable and readily releasable attachment is provided between a gas nozzle and a venturi tube for a burner in a barbecue grill. The attachment is effected such that once the attachment is made between the venturi tube and the gas nozzle it will not become detached during normal operation yet can be releasable for repair purposes. In one embodiment the attachment is provided in part by an attachment member which will be placed over the gas nozzle housing and provide a frictional engagement as well as a guide for an inwardly flanged portion of the air regulator section of the venturi tube. At the same time a rotatable engagement is afforded between the air regulator of the venturi tube and the attachment member.

DETAILED DESCRIPTION I claim: 1.
An attachment member to provide an attachment between a gas nozzle and a venturi member and air regulator member assembly in a gas barbecue grill, the venturi member having at least one lateral aperture and the air regulator member operatively associated with the venturi member to control the entry of air, the assembly also having an opening for receiving the gas nozzle member, the attachment member comprising: retaining means operatively associated with said venturi member and air regulator member assembly to provide linear attachment and linear release between said assembly and said nozzle member with ready release of said assembly from said gas nozzle member, said retaining means including a grommet of resilient material, an end portion of said venturi member or said air regulator member being attached to said grommet in a frictional manner and an inner portion of said grommet having means for releasingly engaging said nozzle.
2.
The attachment member of claim 1 wherein said retaining means includes a body portion having external engagement means and for retentive engagement by said air regulator member.
3.
The attachment member of claim 2 wherein the body portion is of a generally tubular construction having a tubular passageway to provide internal direct contact engaging means and an external annular groove to provide said external engagement means.
4.
The attachment member of claim 3 wherein said body portion includes a circumferential side wall portion of increasing diameter terminating adjacent said annular groove.
5.
The attachment member of claim 4 wherein said side wall member is of a frusto-connical configuration.
6.
The attachment member of claim 4 wherein the largest diameter of said increasing diameter wall portion is adjacent said annular groove.
7.
The attachment member of claim 6 further including an annular wall portion extending outwardly from said body portion and forming a portion of said annular groove.
8.
The attachment member of claim 7 wherein said resilient material is of a rubber composition
