Abstract: A releasable suction cup is formed with a tab formed integral with its rim, and with a release filament attached to the tab. On assembly of the suction cup with a panel to be mounted to a smooth surface by the suction cup, the release filament is threaded through a hole in the panel so that an end of the release filament is accessible adjacent the panel surface that is opposite from the suction cup. When the panel is mounted with the suction cup to the smooth surface, the suction cup can be released by pulling on the accessible end of the release filament. A second embodiment of the invention consists of a double-sided suction cup wherein each cup member has a tab with a release filament attached to its tab and threaded through a hole in the panel to be mounted to a smooth surface. With one side of the double-sided suction cup attached to the smooth surface, the release filament connected to that suction cup side remains accessible through the panel to be pulled to release the suction cup.
