Abstract: The invention relates to a cable clamp for fastening a cable onto a cable spool. The side of a spool is connected to a central tubular member and a clamp of square or similar section having a surface approximately equal to the diameter of the cable is disposed in working relation to the cable. A slot is formed of the clamp slightly larger than the diameter of the cable strand and has a length approximately equal to the size of the cable clamp. Screws are provided to extend through to the clamp interior for urging the cable in position with respect of the spool.
