Claim:
An anti-rotational dead cable end comprising: a housing having a housing interior, a housing mouth, and at least one anti-rotation pin passage, the at least one anti-rotation pin passage near the housing mouth; at least two collets, each collet having: a conical exterior; a lengthwise collet gap; and a collet cable passage for allowing a cable to pass through the collets freely when the collets are in a relaxed state; collet receptacles, each of the collet receptacles cooperating with a respective one of the at least two collets, each collet receptacle having a conical cavity for cooperation with the conical exteriors of the collets, the collets and corresponding collet receptacles sequentially residing in the housing interior; the collet receptacle nearest the housing mouth having at least one anti-rotation pin slot alignable with the anti-rotation pin passage; a collet retainer including a retainer cable passage for allowing the cable to pass through the collet retainer and configured to connect to the housing mouth for retaining the collet receptacles and the collets in axial compression in the housing for advancing each collet into the respective collet receptacle to urge the collets to a compressed state to squeeze the cable residing in the collet cable passages to resist removing the cable from the dead cable end; and an anti-rotation pin residing in the anti-rotation pin passage and engaging the anti-rotation pin slot for preventing the collet receptacles from rotating when the collet retainer is tightened.
