ABSTRACT:
A tool is disclosed that is useful for manipulating the cotter keys that secure the connections between insulators in a high voltage transmission line. In a preferred embodiment, the tool (10) comprises an arm (12) having a first end (14) adapted for connection to a handle (40), and a second end (16) that includes an insert (30) projecting towards the first end. The insert is adapted for insertion into the passage in an insulator so as to engage the split end of a cotter key for partial removal of the cotter key. In a further embodiment, the second end of the tool includes a flange (32) having a concave surface (34, 36) adapted to engage the rounded end of a cotter key and push it back into an insulator.
