Abstract: A hinge assembly for removably mounting a cover to a bed on a truck comprises a mounting assembly and a hinge element. The mounting assembly clamps to the bed and has a guide pin protruding therefrom. The hinge element attaches to the cover and has a guide slot into which the guide pin fits. The guide slot in the hinge element allows the cover to pivot between a closed position, in which the cover overlies the entire bed, and an open position, in which the cover is inclined relative to the bed. The guide slot has an opening so that the hinge element can be detached from the guide pin, thereby allowing the cover to be detached from the bed.
