In a preferred embodiment, there is provided a molded one-piece foil block having a hinged cover as a part of the unitary molded unit, shaped for the cover to clamp downwardly upon each of electrical lead wires and electrically conductive strip normally known as foil, and in the clamped state the cover by virtue of the shape thereof and of the block, snapping into a locked state, and a surface of the block or cover carrying contact adhesive masked by removable masking sheet, the block and cover and hinge interconnecting the two, all being of polypropylene plastic of a substantially flexible nature, and opposing faces of the block and cover in a clamping state, having a plurality of randomly raised portions positioned to substantially mesh with one-another in the clamping state whereby the clamped foil and lead wires are caused to be integrally pressed into improved electrical contact with consequent improved transmission of electric current from one to the other, and the block and cover jointly being further shaped as to firmly grip the lead wire inserted thereinto against the possibility of jerking action thereon disturbing seated wires thereof in electrical contact with the foil.
