A hydraulically damped mounting device has two anchor parts, in the form of a sleeve and a tube, connected together by a resilient wall. The resilient wall and the sleeve define a working chamber for hydraulic liquid which is connected to a compensation chamber by a passageway. The passageway may extend directly through the tube or peripherally of the sleeve. The compensation chamber is bounded by a bellows wall, permitting the volume of the compensation chamber to change freely as vibrations of the tube relative to the sleeve change the volume of the working chamber, without the bellows wall being subject to tensile stresses. The sleeve may be formed in two parts which are forced together during manurfacture, enabling a compact construction to be achieved.
