<p>A fixing plug (1) comprises an inclined ramp (3) increasing in thickness towards the insertion end of the plug (1), and an expanding wedge (4) which can be engaged with the ramp (3) and which forms with the stay bolt (1) a circular cross-section in the non- expanded state. To enable the plug to be produced easily and positioned without any trouble, the thin end (5) of the expanding wedge (4) is moulded onto the end of the bolt (1) as a straight extension thereof, by means of an elastic web (6); and before being inserted in the dowel hole (7) in the wall or ceiling it is pivoted into the wedge- shaped bed (3), by bending the web (6). To make the bent over web (6) exert tension on the wedge (4), the web (6), over a length of 1/2 to 2/3 the diameter of the bolt from the moulding on point at the insertion end (2), is somewhat thicker in cross-section than over its remaining length to the end (5) of the wedge. At its rear end, the plug (1) has a head (9), or cable clip, eyelet, hook or flange to receive components such as claddings, pipes, cable leads or the like. The plug (1) is made from hard elastic plastics material. <IMAGE></p> |
