ABSTRACT:
A wire retaining clip has a mid-portion extending across the back of a vineyard post and forwardly extending arms with helical turns on the ends thereof. The retaining clip is engaged with a tensioned, horizontal trellis wire so that the trellis wire is bent sharply rearwardly of the front edges of the post and is locked into the turns of the clip. The retaining clip prevents the trellis wire from pulling away from the front of the post, prevents movement of the post along the length of the trellis wire and utilizes the tension of the trellis wire to restrain twisting of the post. An installing tool provides for easy installation of the retaining clips.
