ABSTRACT:
A coupler for a corrugated pipe in which several elements thereof can be handled as a single assembly body, and which can be coupled to the corrugated pipe through a simple process. The coupler includes a coupling base, a guide member, a compression ring, a force-fitting member, a sleeve and a cap nut. A through hole, a compression hole and an insert hole are continuously formed through the coupling base. The guide member is inserted into the insert hole of the coupling base. The compression ring has an opening such that the compression ring is elastically expanded or contracted in diameter. The compression ring is fitted into the insert hole of the coupling base. The force-fitting member is fitted into the insert hole of the coupling base. The sleeve is inserted into the insert hole of the coupling base. A passing hole having a diameter corresponding to the diameter of the peak portion of the corrugated pipe is formed through the sleeve. The cap nut has a threaded hole threaded over the coupling base, and a coupling hole fitted over the protruding part of the sleeve.
