Connecting flange portions are form fitted in one piece with an essentially hollow profile at the end of a duct wall portion of a duct section formed from sheet metal. Supporting arms of the connecting flange portions extend back to the duct wall, and are folded into folding pockets which are formed from the duct wall. To attach intermediate connectors having larger duct cross-sections, the supporting arms can have outwardly extending protrusions.
