The invention relates to a cover for a surface drainage device or similar hollow body that is to be embedded in the ground and to be opened. The cover comprises an upper surface over which pedestrian and/or vehicular traffic can pass, and at least one locking element that is attached to an underside of the cover such that the upper side is closed over the locking element. The locking element is disposed at a specified distance from the underside in such a way as to form an air gap for thermal insulation between the underside and the locking element.
