An enveloping corrugated pipe (1) comprises corrugated sections (3) which are disposed one after the other in the direction of the axis (2), extending over more than half its periphery. Further, it comprises corrugated partial sections (3", 3'") which are disposed one within the other, which are turned towards each other and adjoin the ends of the corrugated section (3).
