ABSTRACT:
A tamper indicating cover for a nut securing a gas supply line pipe to a gas meter is disclosed. The cover includes a pair of "C" shaped mating cavity sections which are made of plastic and which are shaped and sized to fit around the top, sides and bottom of the nut and a metal hinge clip which is adapted to be permanently snap-locked into the lower end of each cavity section. The upper end of one cavity section is secured to the upper end of the other cavity section either by a metal clip which is adapted to be snap-locked into each end, if permanent coupling is desired, or a wire seal which is inserted through an opening formed at each end, if non-permanent coupling is desired.
