Abstract
Abstract The device of the invention is provided with a pair of patches each comprising a resilient, foldable annular frame and a piece of cloth stretched over and fixed to the frame. The patches are so arranged as to face each other across a gap and sewed together concentrically with a thread slightly inwardly of the outer circumferential edge thereof in such a manner that as the thread is pulled, the two patches are moved so as to approach each other.
