Abstract
This invention concerns a device for establishing an electrically conductive connection between flat areas of two components which are made of metal with a substantially non-conductive coating and are held together by a nut and bolt through aligned boreholes. An electrically conductive connection with damaged areas on surfaces not visible from one side is made possible by various features, including: the borehole of the component beside the nut is enlarged to serve as a holding aperture; a claw retainer is permanently non-rotatably secured on the free side of the nut and rests with punch-cut claws of side legs on the side of the component which faces the nut; and the side legs of the claw retainer have U-shaped extensions passing through the holding aperture adjacent to the nut having additional punch-cut claws engaging the other component, which is away from the nut, on the side thereof which faces the component adjacent to the nut.
