A sliding type reinforcing bar coupling is provided for simply and firmly bonding a pair of butted reinforcing bars. This device comprises a pair of first segments having semi-cylindrical outer shape with an arch-shape inner base portion to mate with a pair of butted reinforcing bars and a pair of right triangle-shaped sliding edge portions with declined surfaces. A pair of sliding segments has a long trapezoidal bar-shaped flat portion, a dovetailed groove portion along both ends with inwardly declined surfaces for slide-fitting to the right triangle-shaped sliding edge portions of the first segments. The pair of the first segments is overlapped on the pair of butted reinforcing bars. Then, the dovetailed groove portion of the sliding segments is slid into the right triangle-shaped sliding edge portions of the first segments for tightly bonding the pair of butted reinforcing bars.
