Mechanical connection of panels

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to the bonding of wrapping elements, particularly to floor wrapping walls, which is part of a bond: a shingle tower (35) in a side edge (5); a stem (32) formed on a lateral edge (6); and a recess (39) formed in the groove (35) and having a latching surface (16). The joining also includes: a unlocking slider (34) formed on the stem (32) and having a unidirectional surface (26); and interfaces (14, 24) formed in the groove (35) and the stem (32), and serve for support members (16, 26). In the present invention, a relief (40) is formed at one of the side edges (5), which defines a peripheral surface (11) perpendicular to an upper side (3) and an interface (12) parallel to a top side (3). At the other side edge (6) an upper stem (30) is formed, defined by an interface (22) parallel to the upper side (4), a perpendicular surface (21) to an upper side (4) and an upper side (4). The peripheral surfaces (11, 21) of the interfaces (12, 22) and the upper side (3, 4) are attached to the bonded bond state. ŕ
