Abstract: A coupling device for joining the ends of rebars in an overlapping relationship which can be utilized to join the end of one rebar to another which cannot be directly reached, which essentially comprises a body having two elongated and parallel, side-by-side, cylindrical sockets therethrough having a size within which two rebars can be tightly inserted from opposite directions. The edge of the body forming the entrance ends of the sockets being flared out to facilitate insertion of the rebars, and the sides of the body forming the sockets having slits cut therethrough with the edges of the sheet metal adjacent to the slits facing away from the entrance end of the sockets being curved inward to engage the edges of the rebar and lock them in place.
