ABSTRACT:
The invention is a two component, shock-absorbing cable connector to secure a workman to a vertically-suspended safety cable; the first component, a U-shaped shoe, is placed upon the cable with the cable at the crotch of the shoe; the second component, a head combining a slide bar, cams and a handle, is fitted and latched between the sides of the shoe with the slide bar bearing against the cable; the cams include a face engaging the slide bar and outward arms connecting with the handle; these cams operate in unison to press the slide bar against the cable responsive to downward movement of the handle; the handle is attached by a lanyard or other connector to a safety belt or harness worn by the workman; thus, a fall of the workman will be checked by the connector as the weight of the workman pulls the handle downwardly to shift the cams, forcing the slide bar against the cable and squeezing the cable between the shoe crotch and the slide bar.
