A safety device for blocking a fuel line leading from an automobile gas tank having an outer elongate sleeve passing through the wall of the gas tank and having a lateral hole therein opening into the gas tank, and a tubular assembly slidable within the sleeve. The tubular assembly features a lateral opening which, at a given position of the assembly within the sleeve, opens through the lateral opening in the sleeve into the gas tank. The tubular assembly has a stop at one end limiting its movement toward the outside of the gas tank by engagement with the sleeve and has a peripheral constriction at one point for breaking during a violent collision, whereby the openings in the sleeve and the tubular assembly are not aligned and fuel cannot escape from the gas tank during such collisions. |
