a strain relief and cable retention assembly for retaining a cable to a casing includes an anchor made of a flexible material . an internal bore along an axis of the anchor is sized to fit an outer jacket of the cable . tabs extend away from the bore along axes perpendicular to the axis of the bore . a plate made of a stiff material extends along the tabs of the anchor . a section of the anchor passes through the plate such that the plate rests flat against the tabs between the tabs and a face of a casing . reinforcing fibers from the cable are tied around the plate and the tabs , distributing stress from the cable to the plate and casing .
