Estimating the term…
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.
A liquid combustible gas cartridge, comprising a container having an opening blocked by a valve, the said valve having a circular radial bottom wall which supports a central shut-off device and a lateral cylindrical axial wall which has, at its connection to the container, an annular groove surmounted by an annular bead, wherein the axial wall has at least one radial coupling means having at least one radial tooth intended to interact with complementary radial coupling means having at least one radial notch provided in a rotary ring of a connecting device for gas equipment, enabling the device to be moved from a locking position wherein a plurality of ribs provided in a coupling ring of the connecting device are engaged in the annular groove to a release position by the rotation of the cartridge wherein the plurality of ribs are disengaged from the annular groove.
