A locking device composed of two strips of metal bent into specific configurations to provide a tamper-proof assembly when emplaced on a lidded container. One strip is fixed to the container by a concealed screw within the container. The other strip overlies the lid and includes a portion superposed over a portion of the one strip. The aforesaid portions of the strips are provided with registered holes through which the shackle of a padlock is threaded to lock the assemblage in place and prevent the opening of the lid. The invention is applicable for locking any lidded boxes or containers, e.g. electric meter wiring cabinets, to prevent the tampering with elements within the box such as service wires interposing an electric meter between power lines and house lines.

A tamper-proof locking device mountable on a lidded container or the like comprising a first member and a second member, said first member comprising a generally zig-zag strip having three substantially right-angled bends, so that said first member is divided into four sections, with none of said sections being directly opposite to another section, an inner one of said sections being provided with at least one opening, said second member comprising a strip having a generally U-shaped section and a projecting section, said U-shaped section having a first leg and a second leg, said projecting section extending laterally outwards from and substantially perpendicular to the lower end of the first leg of said U-shaped section and being provided with at least one opening, the second leg of said U-shaped section being provided with a threaded bore, and screw means extending through the bore in said second leg, so that the locking device is mountable on a lidded container by placing the U-shaped section of the second member on a wall of a container with said legs straddling said wall and with said second leg and said screw means within the container, turning said screw means until the tip of said screw means contacts and presses against the wall of the container, closing the lid of the container so that the edge of the lid rests on the base of said U-shaped section, and mounting said first member on both the edge of the lid and the projecting section of the second member with one end section of the first member extending over the edge of the lid, one inner section of the first member overlying the first leg of the U-shaped section, the other inner section of the first member overlying the projecting member and the other end section of the first member extending over the tip of the projecting section of the second member, so that said members are attachable to each other by lock means having a shackle extending through the opening in said inner one of said sections of said first member and the opening in said projecting section of said second member.
