PURPOSE: A device for connecting for a spirally corrugated tube made of synthetic resin is provided to secure perfect water tightness in a connection part of a spirally corrugated tube under a complicated and inconvenient working site by carrying out the connection of the spirally corrugated tube in a short time. CONSTITUTION: A device(5) for connecting for a spirally corrugated tube made of synthetic resin includes a connection flange part(6) and a tube insertion part(7), wherein packing grooves(5a) are formed with a predetermined width and depth along an outer periphery of a tube insertion hole(7a) in the center of a front surface of the connection flange part, and a narrow supporting part(5b') is formed at a foremost front part of a spiral groove(5b) formed on an inner surface of the tube insertion hole, so that a spiral protrusion(2) of the spirally corrugated tube(1) is closely inserted in the narrow supporting part to stop rotation of the connection device.
