Abstract
A safety device prevents access to the gas valve of a propane tank. The device includes a cup which fits over the valve, and a locking device for preventing the cup from being lifted from the valve. In some embodiments, the device includes a handle which allows the tank to be carried easily while the safety device is installed. In at least one embodiment, there is no handle. The device prevents children, and other unauthorized persons, from operating the valve, and thus prevents the accidental release of flammable gas.
