The quick-clamping locking plate for a video or film camera has a dovetail guide and straight guide edges approaching one another conically in the direction of the front end of the plate, and a locking arrangement for locking an insert part fastened to the camera in the dovetail guide. In the region of one guide edge of the dovetail guide, one abutment region of the said dovetail guide is constructed as a rocker which is pivotable about an axis perpendicular to the floor of the dovetail guide and has a guide edge which projects into the inner region of the dovetail guide, slightly above the rest of the guide edge on this side of the said dovetail guide. A pressure piece of the locking arrangement is situated behind the dovetail guide and is guided along the central longitudinal axis of the said dovetail guide.
