Abstract
A fitting for retaining an electric cord having a generally cylindrical conduit body with a central bore is threaded at first and second ends thereof. The first end of the body has a plurality of fingers extending in an axial direction therefrom, each of the fingers being spaced from adjacent fingers and terminating at a free end thereof in a wedge-shaped gripper extending normal to the axial direction. A flexible, generally cylindrical gland is disposed within a mating recess formed in the central bore of the body. The recess has a lower annular seat formed about the periphery of the central bore proximate the origin of the fingers, the lower annular seat tapering toward the second end as the seat extends radially outward. The recess is further defined by an upper annular seat formed on an inside surface of each of the wedge-shaped grippers. A sealing nut, which is threadedly received on the first end of the body, urges the wedge-shaped grippers radially inwards and downwards toward the second end as it is tightened, thereby pressing the gland against the cord.
