Abstract: Disclosed therein is a joint device for a corrugated pipe. A socket pipe in which a packing is forcedly inserted is joined to a non-corrugated part of the corrugated pipe and the non-corrugated part is expanded at the position of the packing, so as to keep airtightness in a pressed state of the packing. The joint device has a guide groove formed on the outer circumference of the socket pipe, a connector fit to the socket pipe, and a movable bolt screw-coupled to the outer face of the socket pipe and forcedly joined to the guide groove, so as to freely rotate the connector independently from the corrugated pipe.
