A reinforced rod coupler with reinforced tensile strength is provided to rotate easily when a worker fastens reinforced rods with hands or tools by employing a slide prevention portion. A reinforced rod coupler(50) with reinforced tensile strength comprises a threaded portion, a tensile strength reinforcing portion(54), and a slide prevention portion(56). The coupler links two reinforced rods with each other mechanically. The threaded portion is formed on an inner peripheral surface(53) located in a hollow part of the coupler through which the reinforced rod is inserted. The tensile strength reinforcing portion is formed at the center on an outer peripheral surface(55) of the coupler. The tensile strength reinforcing portion formed at the center of the coupler is thicker than two edge portions of the coupler. The slide prevention portion is formed on both edges of the coupler.
