A fastening plate for the fastening of a fitting to a supporting wall including a bottom plate, provided with two boreholes for fastening screws and with two base-like elevations, and a top plate, at least partially covering the bottom plate, and having an elongated center piece with devices for the fastening of the fitting and at the sides wing-like protrusions provided with oblong holes whose center lines are at right angles to the center line of the center piece and which are also penetrated by the fastening screws with base-like elevations engaging the oblong holes of the top plate as guide pieces. The boreholes lie on the center line of the bottom plate with a spreading dowel-like extension being formed on one borehole and with the other borehole bearing in its base-like elevation a pre-mounted screw sized so that its thread cuts into the wall of the borehole provided in the supporting wall.
