The invention concerns a device for connecting a gas-operated appliance on a gas cartridge valve (23) comprising; a valve body (2) integral with the gas-operated appliance; an axial coupling ring (3) integral with the valve body (2) having at least one elastic tab (4) capable radially of being engaged in an annular groove (27) of a valve of the cartridge; a locking rotary ring (10) capable of occupying a locking position wherein the rotary ring (10) maintains each elastic tab (4) engaged in the groove (27) and an unlocking position wherein the rotary ring (10) allows each elastic tab (4) to be released from the groove (27), and a cylinder (16) provided with a conduit (18) capable of clearing a valve shutter. The invention is characterized in that the rotary locking ring (10) has radial coupling means capable of co-operating with complementary radial coupling means provided on the gas cartridge valve (23) enabling, through rotation of the cartridge, the device to be shifted from a locking position to an unlocking position.

Ce dispositif de connexion pour un appareil à gaz sur une valve (23) d'une cartouche de gaz comprend : - un corps de robinet (2) solidaire de l'appareil à gaz, - une bague d'accouplement (3) axiale solidaire du corps de robinet (2) présentant au moins une patte élastique (4) radialement susceptible de s'engager dans une rainure (27) annulaire d'une valve de la cartouche, - une bague rotative (10) de verrouillage pouvant occuper une position de verrouillage dans laquelle la bague rotative (10) maintient chaque patte élastique (4) engagée dans la rainure (27) et une position de déverrouillage dans laquelle la bague rotative (10) autorise le dégagement de chaque patte élastique (4) de la rainure (27) et, - un cylindre (16) muni d'un conduit (18) susceptible d'effacer un clapet de la valve. Selon l'invention, la bague rotative (10) de verrouillage présente des moyens d'accouplement radiaux susceptibles de coopérer avec des moyens d'accouplement radiaux complémentaires prévus sur la valve (23) de la cartouche de gaz permettant, par une rotation de la cartouche, de faire passer le dispositif d'une position de verrouillage à une position de déverrouillage.
