A locking ring formed of a plurality of curved clamp portions connecting in an end-to-end relationship for securing an electrical power measuring device with a mounting base is disclosed. The semi-circular clamp portions are molded from a single piece of plastic, are identical in construction and are fully interchangeable. Each clamp is preferably formed with a semi-circular curved arc body having a male connection at one end and a female connection at the other end. The male end is formed with a pair of projections of which the first male projection serves as an alignment guide during make-up and use while the second male projection carries a movable latch shoulder for effecting the end-to-end connection with the adjacent mating clamp portion. The female end includes a housing having a central opening with separated first and second entrances formed by a roof mounted lug. The lug also forms a locking surface for engaging with the latch surface of the second male projection of the adjacent clamp portion to operably connect the clamp portions. A tampering indicating locking block is forced into the second entrance after the clamp portions are connected to block movement of the second male projection that would disengage the latch shoulder.
