The fixing clamp serves for the connection of sheets with different expansio n properties and is thus installed in a rectangular opening (16) on the suppor t plate (15), parallel to the plate edge (19) such as to displace. The fixing clamp comprises a rectangular baseplate (1) made from spring steel with a threaded sleeve (2) in the centre for screwing in a screw. Two transverse we bs (5) are bent up in the same direction as the threaded sleeve (2) on the fron t transverse edge (3) and then two clamping legs (6) are bent away from the sleeve, parallel to the baseplate (1), which may be introduced into the opening (16) on the support plate (15) and fixed on the rear side thereof. A further clamping leg (10) is bent upwards on the opposing rear transverse ed ge (4) in the same direction as the front clamping leg (6) and which may be fix ed at the same time to the sheet edge (19) from the outside. In order for the clamps to run transversely in the rectangular opening (16), spring webs (13) are cut into the baseplate (1) on both sides of the threaded sleeve (2) and bent upwards at an angle in the same direction as the clamping legs (6). The spring webs (13) are bent approximately perpendicularly downwards with the e nd regions thereof (14) reaching the baseplate (1), whereby the separation "A" between the end regions (14) and the transverse webs (5) on the front clampi ng leg (6) is of such a size that the spring webs (13) extend into the opening (16) when the front clamping legs (6) are situated on the longitudinal edge (17) of the opening (16). |
