Abstract: An electrical clamp connector having two body halves molded of insulative material and clampable about at least two insulated conductors electrically and mechanically join them together, is provided with a chimney projecting from the clamping side of the base half of the body. A bolt hole in the base body half is threaded to provide the only threaded engagement with the bolt to provide a strong clamping connection without the use of a metal nut or metal plate to distribute stress. The bolt hole extends through the chimney where it is unthreaded and oversized to prevent the transmission of stress between the bolt and the chimney.
