Abstract
A panel having a core, a top side, a underside, a first edge pair and a second edge pair. The first edge pair has a groove profile at a panel edge and a complementary tongue profile at the opposite panel edge, which cooperate in positively locking relationship so that movement of locked panels away from each other in the plane of the panels is opposed. At its opposite panel edges the second edge pair has a receiving hook and a complementary arresting hook. The arresting hook can be assembled to the receiving hook by a joining movement in a direction perpendicular to the panel plane. The receiving hook has a holding groove for a separate locking element for a vertical locking action. At a corner of the panel the tongue edge of the first edge pair comes together with the receiving hook. The holding groove provided on the receiving hook of the second edge pair for the locking element has an upper groove wall with a spacing from the top side that is greater than the spacing between the panel top side and the tongue top side of the tongue profile of the first edge pair.
