ABSTRACT:
A fixing plug contains a metallic expanding sleeve having a slotted end portion or section. Engaging with this slotted end portion is an expanding element which contains a body formed of an oscillation damping material and in which there are embedded a conical sleeve and in axial spacing therefrom a connection element or part. The conical sleeve coacts with the slotted end portion. The connection part serves for the attachment of an attachment screw of the like and for drawing the expanding element into the slotted end portion of the expanding sleeve. At the end portion located opposite the slotted end portion there is arranged an internal lining formed of an oscillation damping material. This internal lining or covering is constructed as an insert body member and possesses a part which protrudes past the expanding sleeve. The fixing plug affords both good attachment properties and good oscillation damping properties.
