A strain-relief device for use in a cable splice case for communications cables comprises a horizontal portion having a plurality of tangs projecting therefrom, a vertical portion projecting upwardly from said horizontal portion, and reinforcing means between said horizontal and vertical portions. The tangs on the horizontal portion grip the outer sheath of a communications cable, while the vertical edge abuts the interior end of a cable collar extending through an end plate. The device relieves strain in the cable by allowing it to pass through to the outer shell of the cable splice case.

Strain-relief brace for cable splice case

A cable splice case for communications cables comprises a two part outer shell, divided perforate end plates, and a cable collar for each cable end. The cable collar is grooved to receive an end plate gasket. A preferred form of cable collar is in two parts and fits together over a mastic winding between two washers on the cable to form a hermetically sealed cable end structure which is retained during reentry of the splice area. Details of gasket, tie bar, and strain relief structure are given.
