Abstract
The present invention is a retaining device for maintaining a collapsible tube in a rolled condition. This retaining device is for placement over the rolled portion of a flexible tube and is made from flexible material which molds to the shape of the tube bottom. The shape of the retaining device is such that it does not interfere with the storage or use of the collapsible tube. A gripping tab may be provided to aid in both the removal of the device from the tube and the placement of the device on the tube.
