Disclosed is a coupling device of a corrugate pipe to quickly and conveniently couple and separate a corrugate pipe and in particular, increase coupling rigidity of the corrugate pipe. The coupling device of a corrugate pipe comprises: a coupling socket accommodating an end portion of a corrugate pipe, and provided with a coupling protrusion in which a through hole is formed on an external surface in a dead end; a fixing block transversely inserted into and coupled to the coupling protrusion, wherein a front end penetrating through the through hole is inserted into a valley portion of the corrugate pipe; and a locking plate coupled to the coupling protrusion in an axial direction, and preventing the fixing block from being left in a radial direction. 파형관의 연결 및 분리작업을 신속하고 간편하게 할 수 있고 특히 파형관의 연결 강성을 증대시킬 수 있는 파형관 연결장치가 개시된다. 상기 파형관 연결장치는 파형관의 단부를 내부로 수용하며, 끝단 외면에는 관통홀이 형성된 체결돌부가 구비되는 연결소켓과, 상기 체결돌부에 횡방향으로 삽입 결합되며, 상기 관통홀을 관통한 선단이 파형관의 골부에 삽입되는 고정블록 및, 상기 체결돌부에 축선방향으로 결합되며, 상기 고정블록의 반경방향 이탈을 차단하는 록킹플레이트를 포함할 수 있다.
