A busway structure which contains a device for connecting insulated bus bars. The device has a T-shaped bushing inserted through apertures in busway members to be connected. The T-shaped bushing has a threaded bore into which is screwed a mating bolt. The bolt head rests on an O-ring cap so that tightening the bolt forces the O-ring cap against the outer surface of one bar member and compresses the head of the T-shaped bushing against the outer surface of the other bar member for firm engagement therebetween of the bus bar members. Preferably, the T-shaped bushing extends through all bus members being connected and into the interior chamber of the O-ring cap.
