ABSTRACT:
A fastening dowel for fastening objects to tiled plasterboard walls includes a shaft portion with expansible legs, a neck and an end flange adapted to rest against an end face of the wall. In order to prevent water from penetrating the plaster wall when the fixing dowel is used in "wet" rooms, the neck of the fixing dowel is provided with a circumferential groove which extends to both sides of the front face of the plasterboard wall, once the fixing plug has been pushed into the drilled hole, and comes to rest in the region to be sealed. A sealing composition can be injected through an injection aperture, formed in the end flange, and a longitudinal channel which opens into the circumferential groove.
