A new screen characterized by the fact that the flexible sheet constituting the screen has an extension in its lower mouth which extends below the base of the frame and remains in this position without leaving the edge of the base of the aforementioned frame through an annular elastic element disposed at the edge of the lower mouth of the flexible sheet forming the hood of the screen which annular elastic element by its own antagonistic pressure against the flexible edge of the fabric constituting the cap wrinkling which makes it once passed the edge of the base of the frame at the time of its placement in the same shrink said mouth by virtue of the antagonistic action of the constrictor annular element avoiding the possibility that the mouth of the cloth cap of the lamp may accidentally leave the frame and also keeping the fabric tight on the frame which flexible sheet to be removed from it is enough with opening the mouth of the base of the flexible laminar bell and overcoming the constrictor action of the opposing elastic annular element the opening of the folds of the shirring formed by said elastic element in contraction is made and the maximum opening of the mouth the bell.
