ABSTRACT:
A device providing an insulating support for an electrical conductor includes a body having a through bore with an upper, cylindrical portion and a lower, threaded portion. A hook extends integrally from the upper end of the body over the upper end of the cylindrical bore. A piston in the cylindrical bore has an upper end for mating engagement with the hook to define a fully enclosed passageway surrounding the conductor upon movement of the piston from an initial position, wherein the conductor may be moved laterally to a position between the hook and the upper end of the piston, to a terminal position wherein the conductor is fully surrounded by surface portions of the hook and piston. A threaded insert is engaged in the threaded portion of the body axial bore. A passageway through the insert has a one-way valve for injection of silicone gel into the cylindrical portion of the body bore to move the piston from its initial to its terminal position. An internally threaded, blind bore in the insert is provided for mounting the device on a threaded shaft such as those conventionally positioned on utility poles.
