ABSTRACT:
A corrugated tube consists of a one-piece metallic basic body with corrugations arranged concentrically about the tube axis and one behind the other, which corrugations each have an annular space in the radial zone between the corrugation trough and the corrugation apex. This annular space is closed at its interior by means of two mutually concentric annular wall parts which are seated on one another and are relatively slideable one within the other in the axial direction. On the axial side remote from the associated corrugation the annular wall parts adjoin a radial annular space which is opened towards the tube interior and dimensioned as narrowly as possible as regards its radial and axial width.
