PURPOSE: To firmly fix furniture and office or electronic equipment to a wall or floor and prevent it from overturning by connecting at least a pair of suction cup bodies together back to back with each other, which are molded out of elastic material almost into cup shape.

CONSTITUTION: A pair of suction cup bodies 1, the back surface of which are mutually connected by a connecting member 2, are integrally molded into cap shape out of elastic material such as rubber or soft resin, and the connecting member 2 is formed of a highly strong resin or metal. In case of resin, the connecting member 2 is integrally molded with the bodies 1, in case of metal, both the ends are inserted into the bodies 1 when the sucker bodies are molded, and in both cases, it is deflected, when a large impact is added, to absorb the impact. When one or a plurality of suction cups are preliminarily interposed and sucked between a member 3 to be fixed and a wall or floor, the connecting member 2 absorbs the vibration or impact even when the floor surface is vibrated, so that the member 3 to be fixed or articles housed therein are never broken.
