The panel has a connector including a base part with side and standing surfaces. The base part face toward a base, and is in partial contact with an inner surface of a lip (15) and base of a locking arm (14) before and after mating plate-like building panel parts (1.1, 1.2). The inner surface of the lip is arranged below a pointed or right angles at the base and/or base surface of one of the panel parts. A planar pressing surface of a locking element (20) pushes against a header (5.3) during the connection of the panel parts, so that the header is pivoted toward a groove base. |
