Uniclamp, a simple, durable, and easily installed device used currently for oceanographic work permits mechanical loads to be attached to an oil-well, logging-type cable containing coaxial electrical leads, and it has the desirable feature of bearing loads up to the ultimate strength of the armored cable. This clamp secures the armor between a slightly tapered hollow spindle within the cable and a similarly tapered external block. This device is easy to dismantle and to reuse.
