A double suction cup holder in which the two suction cups are connected by a stem has a longitudinal air passageway through the stem connecting the two cups. A diametrical opening traverses the passageway and has a valve member rotatably mounted therein which has inter-communicating longitudinal and diametrical bores. When the valve is turned so that its diametrical bore communicates with the air passageway, the vacuum in the cups is spoiled releasing the holder.

A double suction cup vacuum holder comprising first and second arcuate suction cups, each having a spherical concavity with a flexible circular lip around said concavity; a connecting stem coaxial with said cups; a circular longitudinal air passageway extending through said stem and communicating with the interior of each cup; a diametrically extending bore in said stem intersecting said passageway; a valve member rotatably mounted in said bore; said member having intersecting axial and diametrical bores therein, with the axial bore extending in the valve member to an unobstructed opening leading to the exterior of the device, so as to spoil a vacuum in said cups when the diametrical bore of the valve member is placed in communication with said air passageway, with said valve member acting to block passage of air in the longitudinal passageway between the interiors of the two suction cups when the valve member is rotated to a position in which the said diametrical bore is not in communication with said air passageway.
