Abstract: The invention regards an apparatus for mounting a flat screen on a surface wherein the flat screen comprises at least two fixtures. The apparatus comprises, two mounting members adapted to be attached to the fixtures on the flat screen and a wire with one end connected to one of the mounting members and the other end connected to the other mounting member. The mounting members comprise an axle adapted for the wire to be coiled around for changing the length of free wire between the mounting members and retaining means at a radially greater distance from the wire coiled around the axle, adapted to retain the wire hereby preventing uncoiling of the wire.
