A set-screw bushing including integral electrical clamp for connection to the end of a threaded pipe, although in some instances the invention is usable with an unthreaded pipe, the bushing of this invention including clamping means for securing an electrical conductor to the bushing. The bushing and the clamping means are preferably cast as an integral unit of metal. The clamping means include a c-shaped member defining an open mouth with a lip to receive various sized electrical conductors. An adjustable lug screw extends into the mouth to secure a conductor to the lip when the screw is tightened. The bushing preferably has a plain or unthreaded inner wall with the bushing being secured over the pipe by means of an adjustable set-screw extending through the bushing wall. A tab extends from the bushing wall to limit the amount of engagement between the bushing and the pipe. The upper edge of the bushing terminates in a rim which has a notch to permit ease of installation or insertion of an insulating piece within the bushing and against the rim. With the present invention the bushing is quickly installed on the pipe with the set-screw forcing the tab against a thread of the pipe to achieve a tight grip.
