An end fitting for a gas hose 23, for releasably connecting an appliance to gas supply pipework. In use, the end fitting connects to a valve (17) of the gas supply pipework, a projection 25; 29; 32 of the end fitting forcing a valve member 21 off its seat 20 in order to allow gas to flow from a gas supply into the hose and thence into the appliance. The end fitting is releasably connectible to the valve 17 by way of a bayonet fitting. At least a part of the bayonet fining or the projection of the end fitting is of a material having a lower melting point than the remainder of the end fitting. Melting of this part, for example in the event of fire, results in the valve member 21 returning to its seat 20, thus causing the valve 21 to close automatically.
