Such an operation results in the formation inverted V-shaped hollow to the lower extremity 5 of a loop I9 in the tap wire I8, the loop 19 being of one leg thereof, a groove of substantially semicircular cross-section extending longitudinally along the inner surface of said one leg and merging with said lower opening, and an upper opening of substantially circular cross-section extending from the juncture of the legs of said V- shaped hollow in axial alignment with said lower opening, said tap wire extending upwardly into said body portion through said lower opening and emerging from said body portion through said upper opening, that portion of said tap wire between the lower and upper openings extending along said semi-circular groove.
2. In a clamp for connecting a tap wire to a conductor, a body portion having an inverted V- shaped hollow at the upper end thereof, a clamping shoe movable along said body portion, adjustable means for moving said shoe toward said hollow to clamp the conductor between said body portion and said shoe, and holding means within said body portion for maintaining said tap wire in direct physical engagement with said conductor, said holding means comprising a pair of laterally spaced openings extending upwardly through said body portion along the legs of said inverted V-shaped hollow and in communication therewith, said openings lying in parallel planes which are normal to the axis of said conductor and in intersecting planes which are parallel to the axis of said conductor.
3.
