Abstract
A safety mounting device for a fuel-pump nozzle includes a vertical passage which attaches the nozzle receptacle to the pump casing. The major portion of the passage is located within, but sealed from the casing, but upper and lower vents open outside the casing to induce a throughflow of air which prevents any explosive gas mixtures from the nozzle from penetrating the casing. A closed or vented chamber may be provided between the receptacle and the passage.
