Lockable gas tank cap device

A lockable gas tank device for releasably locking the open end of a gasoline tank of a vehicle, said gas tank cap device comprising

• a cover hingedly affixed to a vehicle in the area of the open end of the gasoline tank thereof in a manner whereby it covers said open end in a closed position and is free from said open end in an open position, said cover having a pair of first and second spaced parallel edges and a third edge perpendicular to and joining the first and second edges;
• a loop-type projection extending from the inside of the cover adjacent the third edge and spaced from the first and second edges, said projection being at least twice the distance from the first edge that it is from the second edge;
• a spring-biased pin biased by a spring and slidably mounted on the vehicle in proximity with the cover for locking the cover in closed position under the force of the spring, the pin being closely adjacent and parallel to the third edge of the cover and extending across the cover from the first edge of the cover into the projection in closed position;
• and
• cable means affixed to the pin and extending into the vehicle for moving the pin out of the projection against the force of the spring to release the cover for movement to its open position.
