Coupling structure for piping is provided to minimize an interference phenomenon between pipes by connecting the pipe with a predetermined angle, and to connect the pipe simply with inexpensive cost. Coupling structure for piping includes a wrinkled pipe(2), a connector member(4), a fastening member(10), and a pressing ring(14). The connector member is connected to both ends of the wrinkled pipe. The connector member has an inner diameter to insert an end part of a pipe(P). A female screw part(6) is formed on an extension direction of the pipe on a location separated from an outer circumference. The fastening member has a male screw part(8) combined with the female screw of each connector member, and has a cylindrical shape. The connector member and the fastening member compress the outer circumference of the pipe.
