Abstract

An inner line () is arranged within and extends with the outer tube () between two port connectors (). Each outer tube part () includes a variable-length outer tube part that can be varied between a compressed state and an expanded state. The connection device () is displaceable in the longitudinal direction (A) relative to the inner line () by a compression of one outer tube part () and a corresponding expansion of the other outer tube part (). A ventilation system with at least one such ventilation tube unit is also provided.
