Abstract
A tubular element of a connecting device is mounted for displacement between an extended position, where it seals against a mobile container around an opening therein for passage of conditioning air, and a retracted position where it is spaced from the container and where the connecting device is entirely retracted from said opening. A valve arrangement of the connecting device includes a body disposed coaxially of the tubular element and forming therewith a passage for the air flow which is opened when said element moves toward its extended position and which is closed when said element moves toward its retracted position.
