ABSTRACT:
A wire tightening device including a clip and a leverage-generating tool therefor. The clip includes a tensioning arm, with an outer end having an upwardly-extending crook, and a retaining arm joined together, and held in axial alignment, by a laterally-extending, winding portion. The winding portion has a pair of legs projecting from the inner ends of the arms and an open loop joining the legs in a spaced-apart relationship. The open loop has an outer diameter greater than the distance between the inner ends of the arms. The leverage-generating tool, on the other hand, includes a handle having a tine and a key at one end thereof for engaging the clip. The key has a vertical member adapted for positioning snugly between the legs of the clip when the tine is inserted into the center of the open loop.
