The invention relates to a coupling endpiece engageable by force in a corrugated end of a corrugated tube having corrugations following one another at a predetermined pitch and possessing a minimum inside diameter and a maximum inside diameter. The endpiece is constituted by a tubular body possessing a first zone provided on the outside with at least two annular barbs of the Christmas-tree type that are spaced apart by a distance corresponding to the pitch of the corrugations of the tube and having a maximum diameter greater than the maximum inside diameter of the tube, the first zone presenting between the barbs a minimum diameter greater than the minimum inside diameter of the tube, and the body has a second zone extending immediately behind the barbs to receive at least one end corrugation of the tube and having an outside diameter less than a diameter of a junction zone between two annular barbs. The invention also provides a corrugated tube fitted with such an endpiece.
