ABSTRACT:
An improved clamp for nonmetallic rope has a plug formed with an annular collar at one end and a plurality of tapered segments formed integrally with the collar and extending outwardly therefrom. The plug has a hollow axial bore defined by a serrated cylindrical surface to increase the gripping effect on a rope telescopically inserted into the bore. The plug is telescopically inserted into the tapered bore of an outer sleeve which compresses the tapered segments of the plug against the rope. The length of the plug is at least ten times greater than the diameter of its bore, which in combination with the annular collar, provides an increased clamping pressure between the serrated surfaces of the tapered segments and the rope throughout the length of the plug. The outer tapered surfaces of the plug segments and the internal bore of the sleeve has a low friction, corrosion resistant coating applied thereto whereby the axial component of the wedging force between the plug and sleeve will be less than the axial component of the friction force between the rope and plug bore preventing slipping of the rope from within the plug bore. The angle of taper of the plug is approximately 4.degree. or less and is equal to or greater than the taper of the sleeve bore.
