Abstract
A device for connecting gas equipment to a valve of a gas cartridge, having a tap body fixed to the gas equipment, an axial coupling ring fixed to the body of the tap and having at least one elastic lug which can engage radially in a groove of a valve of the cartridge, a rotary locking ring which can occupy a locking position in which the rotary ring keeps each lug engaged in the groove and a release position in which the rotary ring allows each elastic lug to be disengaged from the groove, and a cylinder having a tube which can override the shut-off device of the valve, wherein the rotary locking ring has radial coupling means which can interact with complementary radial coupling means provided on the gas cartridge valve, so that the device can be moved from a locking position to a release position by the rotation of the cartridge.
