Safety device for taps provided with a disk shutter sliding in a tubular sector shaped like the arc of a circle, constituting the product outlet duct of a pasteurizing machines used in the production of creams, soups or the like. The shutter disk is connected with an operating lever endowed with a spring pin fitting into suitable hollows obtained on an element with circular sector which is concentric with respect to the rotation axis of said operating lever. Both on the operating lever and in the element with circular sector showing the hollows defining the basic positions of the operating operating lever of the shutter, reciprocal abutment means have been provided, whose purpose is to interrupt the movement of the operating lever on reaching said intermediate position in which a radial opening for product discharge is opened, thus preventing the unintentional overcoming of said position.
