An element for the adjustment of pipes of different diameters, essentially constituted by a tubular body of cement and asbestos paste or cement and other fibers similarly easily sectionable, having a cylindrical portion and a frustoconical or truncated-pyramidal portion that gradually reduces the passage of the tubular body, as it moves away from said cylindrical or prismatic part, so that it can adjust the frustoconical or frusto-pyramidal part externally inside a correspondingly more or less wide tube, through the region of the same of the corresponding amplitude, near which the conical or prismatic part of the element itself is cut so that an excessive reduction of the passage of the conduction takes place.
