摘要

The fastening device (10) has a profile element (12) with a bearing section (16), on which a wall- or ceiling casing element (18) is applied, where one or multiple pretensioning elements (26) are provided to apply a pretensioning force to interlock the wall- or ceiling casing element with the bearing section, if the wall- or ceiling casing element is applied on the bearing section. The pretensioning force is directed to the bearing section. The bearing section is formed by a U-shaped section (14) of the profile element, in which another U-shaped section (20) is positively inserted.
