摘要： A coupling device couples first and second edges of first and second flooring or covering panels. The coupling device includes a projection on at least a portion of the first edge and a groove in at least a portion of the second edge, the coupling device locking the first and second edges one in a first direction perpendicular to the lying plane of the panels and in a second direction parallel to the lying plane. The projection includes first and second retaining appendages, the first projecting from the first edge along an axis inclined by a first angle with respect to the main plane of the first panel, the second being arranged below the first appendage and projecting along an axis orthogonal to the lying plane of the first panel, the groove having a first and second retaining seats counter-shaped with respect to the first and second retaining appendages.
