Abstract: A flexible sheet of material such as plastic film is attached to a supporting surface by a two-piece retainer strip assembly including a bottom strip member and a top strip member extruded from a semi-rigid plastics material and having the same width. The bottom strip member has a recess with undercut portions defined by opposing inwardly projecting protuberances, and the top strip member has an inner portion with outwardly projecting protuberances, one of which is formed with a cam surface. In one embodiment, the bottom strip member has projecting bottom corner portions which assure an air-tight seal between the bottom strip member and the supporting surface.
