A flexible cord-like hollow object for the transportation of media is provided with an inner zone enclosed by a casing. A barrier layer, which is impermeable to volatile molecules of the medium to be transported, is provided on the casing surface facing the inner zone. The barrier layer comprises sub-elements that are arranged in a scale-like manner.

1. A flexible cord-like hollow object comprising a casing (12) extending along a longitudinal axis and having (1) an inner layer (18) with an inner surface (16) encircling an inner zone for the transportation of a medium having volatile molecules and (2) a barrier layer (26), which is impermeable to said volatile molecules of the medium that is to be transported, characterized by the feature that said barrier layer (26) is on said inner surface (16) and comprises sub-elements (30) that are arranged in a scale-like manner and overlap in both the transportation direction of the medium and coaxially relative to said longitudinal axis and further characterized by the feature that said inner surface (16) to which said barrier layer (26) is adhered is treated physically and/or chemically in order to increase the strength of adhesion of the barrier layer (26).
