Abstract A method is disclosed for terminating a cable composed of a multiplicity of wires each preformed with a helical twist. The method includes the steps of: feeding an end portion of the cable to be terminated through a sleeve, gripping the cable at a selected point near the end portion thereof to be terminated; unlaying the end portion of the cable with a minimum of distortion of each unlaid wire from the laid shape so that each outermost cable wire resumes its preformed helical twist about an axis that is different from those of the other wires whereby the wires in said portion together form an envelope that is symmetrical about the cable portion axis and has a circumferential bulge adjacent its inner end, a circumferential flare at its outer end and a circumferential constriction intermediate its ends. The sleeve has a tapered bore whose length and whose major and minor diameters are related to the envelope dimensions so that when the end por- tion is pulled back into the sleeve with the envelope axis aligned with the bore axis the envelope bulge is positioned adjacent the smaller end of the bore, the envelope flare is positioned adjacent the larger end of the bore, and the flaring wire ends lie against and are distributed around the bore wall. The cable end portion is arranged inside the sleeve bore so that the envelope axis substantially coincides with the bore axis. The sleeve bore is filled with a settable material so that it surrounds the unlaid wires, forming a solid tapered plug extending both inside and outside the entire length of the envelope formed by those wires that will wedge against the bore wall when a tensile force is applied between the sleeve and the cable.
