Abstract: An arrangement for releasably fastening a peg in a peg hole, e.g. a chair leg in a drill hole of a chair seat, the peg or the area around the peg hole consisting of wood or other yieldable material. When inserting the peg in the peg hole, one opening of a screw hole made through the peg is mainly located outside the peg hole, the screw hole being directed so that its other opening is mainly located within the peg hole. A screw socket, screwed into the screw hole, has its exterior threads engaging the material of the peg. A pressure plate, mounted over the second opening of the screw hole and adjacent portions of the peg hole, distributes the pressure of a screw, screwed into the screw socket. By means of friction, caused by the tension of the tightened screw, the peg is fixed in the peg hole.
