Abstract
An improved hose for dispensing gasoline at service stations has removable fittings at each end; the removable fittings receive spreaders, each of which in turn receive a bayonet fitting at an end of a vapor recovery tube. An internal collar on an inner portion of the removable fitting and a keeper on the bayonet fitting cooperate to hold the spreader in place. The spreader retains the bayonet fitting on the vapor recovery tube in concentric position at each end of the hose. When the gasoline hose is replaced the vapor tube is removed and the removable fittings are unscrewed; the removable fittings and the vapor tube are then installed in a new section of outer hose and the assembly is re-installed on a gasoline pump.
