Connection device for pipes and conduit elements characterized in that a piece of elastic material in the form of a sleeve whose thickness varies progressively from a maximum located in the center to a minimum at the ends, is located so that it lodges in its interior equally two ends of the conduits or elements to be coupled and in turn is housed in the holes of conical shape of two flanges, so that when both flanges make an approach movement by the effect of their unión screws is a centripetal compression of the elastic sleeve on sliding the conical front surfaces of the flanges on said sleeve, which is adjusted evenly throughout its extension with great force to the cylindrical surface of the pipes to be coupled, producing the tightness of the joint.
