Device for securing an object to a surface by vacuum

A device having an object holder for vacuum attachment of an object to a surface, the object holder comprising:

• a vacuum port;
• a vacuum passage in fluid communication between the vacuum port and a surface of the object holder adapted to engage an annular sealing member of the object to define therewith a vacuum chamber;
• a valve positionable in a closed position to block the vacuum passage and positionable in an open position to allow a negative pressure into the vacuum passage;
• a containment absorber disposed in the vacuum passage;
• whereby the containment absorber is expandable by absorption of moisture so that an expansion of the containment absorber closes off the vacuum passage and equalizes the negative pressure which thereafter actuates the valve to the closed position.

• a valve member attached to the valve which is displaceable to a sealing position in response to expansion movement of the absorber wherein the valve is simultaneously moved to the closed position.
