(54)	An adapter for releasably attaching a cartridge to an appliance

(57) An adapter for use with a gas cartridge comprises a housing having two interengageable parts (12, 14) to enable the housing to be opened and closed about a gas cartridge (26). The upper part (12) incorporates a piercing pin (16), spring loaded sealing piston (17), valve (20), and screwthread (24) to allow an appliance to be fixed thereto. On engaging the parts about a gas cartridge, the sealing piston (17) seals on the surface and the pin (16) pierces the cartridge. Flow of gas from the cartridge is controlled by the valve (20). The adapter enables appliances to be removed from a pierceable cartridge after piercing and to be used with both pierceable and valved cartridges.
