Whistle valve for inflatable balloons, characterized essentially by consisting of a rigid piece of cylindrical configuration with two zones of different diameters, the smallest of which has a tongue of circular shape able to go into oscillation by effect of a current of air projecting from the interior of the previously inflated balloon, and a second piece of double ring shape, of slightly greater diameter than that of the first, destined to receive inside it, retaining in a recess in the form of a throat the lips of the mouth of the balloon, which it is held at least at a lateral point by means of an appendix derived from the annular zone of smaller diameter of the second piece.
