Abstract
An elongated tubular metal body includes a longitudinally extending wedge portion having converging inner surfaces defining an included angle of about sixty degrees for receiving the end portions of concrete reinforcing bars. A series of longitudinally spaced holes are formed within the tubular body in opposing relation to the wedge portion, and a socket head set screw is threaded into each hole. The screws have conical pointed tips for penetrating a bar when the screws are tightened with a preset torque, and the screws force the outer ribs on the bar into the tubular body. A section of cylindrical seamless tubing of ductile steel is cold forged or deformed within a die set to form the tubular body with a generally diamond-shaped cross-sectional configuration, and longitudinally spaced and outwardly projecting ribs may be formed on the body.
