Abstract

A fixing clamp for connection of sheets with different expansion properties and is thus installed in a rectangular opening of a support plate. The fixing clamp includes a rectangular baseplate and a threaded sleeve in the center. Transverse webs are bent in the same direction as the threaded sleeve on a front transverse edge. Two clamping legs are bent away from the sleeve, parallel to the baseplate. A further clamping leg is bent upwards on the opposing rear transverse edge in the same direction as the front clamping leg. Spring webs are cut into the baseplate on both sides of the threaded sleeve and bent at an angle in the same direction as the clamping legs. The spring webs are bent with the end regions thereof reaching the baseplate, whereby a separation “A” between the end regions and the transverse webs on the front clamping leg is of such a size that the spring webs extend into the opening when the front clamping legs are situated on the longitudinal edge of the opening.
