Abstract
A casket lock for a gas utility valve having inlet and outlet conduits includes a pair of mating casket sections releasably connected together along a hinge about which the sections are movable between open and closed positions. In the closed position the casket sections cooperate to define a casket containing the valve and the conduit connections thereto. The casket sections are releasably retained in closed position by a fastener contained within the casket. A tubular lock secured in locked position to the casket prevents access to the fastener.
