"SYSTEM FOR COUPLING WITHOUT WELDING, OF LEAD PIPES OR SOFT MATERIALS" characterized in that it comprises a cylindrical inner sleeve, of a rigid material, of slightly greater diameter than the external diameter of the tube of deformable nature and that is situated around at the end thereof and an intermediate or terminal element of a rigid nature endowed with a tubular end of an external frustoconical shape, threaded triangularly to form a conical thread whose end of smaller diameter is substantially lower than the diameter of the pipe, so that said threaded end is introduced inside the end of the pipe making by relative rotation of both parts, that there is an adjustment of the threaded end inside the end of the pipe to act as a tap on it and without causing external deformation of the pipe , because its expansion is limited by the effect of the external adjustment sleeve.
