ABSTRACT:
A strain relief device is disclosed which is adapted to receive wires which extend into an aperture of a service box. The device comprises a structure formed of a cylindrical segment and a conical segment. The cylindrical segment is disposed at the base of the conical segment and each of the segments is hollow. At least one section line, and preferably two, is disposed through the side wall of the structure. The section line extends from the top of the conical segment to the bottom of the cylindrical segment, whereby the segments are split into two sections. An abutment is disposed on the structure which is arranged to urge against the perimeter of the aperture in the service box. The two sections are joined together with a collar which is disposed around the cylindrical segment and co-acts with the abutment to hold the device in the aperture.
