ABSTRACT:
An improved electrical conductor cover is provided which essentially completely surrounds an energized conductor and is resistant to inadvertent, impact-induced dislocation of the cover during use. The cover includes an elongated, tubular, conductor-receiving section and a pair of ribbed, normally biased-together legs extending from the section. The legs normally are in abutting engagement, but can be separated for positioning the cover on a conductor; the ribs are spaced along the length of the legs and serve to cooperatively maintain the conductor within the tubular section even in the event of an accidental impact normally tending to spread the legs and thus expose the covered conductor. The cover also includes a molded-in-place, threaded head which projects only through the outer surface of the cover for allowing connection of a manipulative handle to the cover without the need for rivets or the like which extend completely through the insulative wall of the cover.
