Abstract: A locking clip for a cable tensioning system, comprising (i) a base plate having a top surface having a gripping portion, tensioning arms extending from the top surface, a cable retaining arm and posts extending from the bottom surface, and, at least one slot in the base plate; and, (ii) a tapering top member including a cable tensioning hook with a channel and extending from the top surface, and at least one nub extending from the bottom surface to slidingly engage the slot. The clip can hold a portion of a sheet between the base plate and the top member when the top member and the base plate are in an engaged relationship. The cable tensioning arm holds the cable and allows tension to be placed on the sheet. When the clip is disengaged from the sheet it can be temporarily attached to the cable by the cable retaining arm.

Abstract: A cable tensioning system for mounting a vinyl sheet to a billboard frame, comprising a cable secured on a frame at one end and secured to a spring-loaded cable tensioning device at the other end. A plurality of cable guides are mounted at intervals around the frame, each of the cable guides having a channel adapted to receive the cable. Portions of the edges of a sheet are secured within a plurality of locking clips around the perimeter, each clip also having a channel to receive the cable. The sheet with the clips affixed is secured to the frame whereby cable travels through the channels in the locking clips and is guided around the perimeter of the frame by the channel guides and secured to the spring-loaded cable tensioning device. The spring-loaded cable tensioning device is deployed to tighten the cable around the frame and secure the sheet to the frame.

Abstract: A clip for use in a cable tensioning system, comprising (i) a base plate comprising a generally flat base member having a top surface having a plurality of surface irregularities, a bottom surface, a front edge and a rear edge, and a pair of opposing tensioning arms extending from the top surface; and, (ii) a top plate comprising a top surface, a bottom surface, a front edge and a rear edge, a lip protruding from a top surface thereof having a channel defined therein, wherein the top plate is adapted to secure an edge of a substantially flat medium between the base plate and the top plate when the top plate and the bottom plate are in an engaged relationship, and wherein the channel can receive a portion of a cable.
