A stopper for bottles and thermally insulating containers, characterized by being formed by a rubber sleeve extrablading, occluded at adjustable pressure between two disks or pieces of bakelite or similar material, thanks to a metal pin provided with a hinged and bent handle, which, passing through the upper part, is threaded into the lower part, so that when the handle is turned and its elbow is supported on the upper part, the lower part is raised, pressing, crushing and widening the straight section of the sleeve.
