An apparatus for connecting corrugated steel pipes is provided to raise the joint efficiency by inserting two corrugated steel pipes into a joint pipe. An apparatus for connecting corrugated steel pipes comprises a coupling pipe(22) and a joint pipe(21). The coupling pipe includes a body having a hollow shape and is coupled with outer end portions of each corrugate steel pipe to be jointed by the coupling pipe. The joint pipe has a protrusion(21a) at the inner wall thereof and a watertight gasket(21b) attached to both sides of the protrusion. A coupling member(23) includes coupling blocks(23a), bolts(23b) and nuts(23c). The coupling blocks protrude from the outer peripheral surface of the coupling pipe. The bolts and nuts allow side sections of each corrugate steel pipe to be in close contact with the gasket by passing through the coupling blocks.
