ABSTRACT:
The present invention relates to a flexible hose, preferably a charge-air hose for automotive vehicles, comprising at least one corrugated portion and a substantially tubular portion which is arranged at least sectionwise within the corrugated portion. In order to facilitate the mounting of such hoses, the present invention is so conceived that the corrugated portion is formed integrally with the tubular portion, and that the tubular portion is introduced, from an extended position in which the corrugated and the tubular portion are arranged in succession, into the corrugated portion by turning said tubular portion outside in.
