A clip for use in a cable system for stretching a sheet across a surface and maintaining it under tension, the clip comprising a base plate and a top plate. The base plate has a pair of opposing retaining arms extending from the top surface and a recessed area defined in the base plate. The top plate has a hook protruding from the top surface having a channel defined therein. The top plate slides between the arms of the base plate and is removably retained therein and the plates engage the edge of a sheet. The hook removably engages a cable and the sheet is stretched when the cable is tensioned. The clip can be retained on the cable when a sheet is to be replaced by partially separating the two plates.
