Beschreibung
Zusammenfassung:	The invention relates to a duct section configured for connecting to one or more other duct sections for creating a duct system for delivering and/or removing gaseous substances. The duct section comprises a circumferential 5 outer wall with an inner surface and an outer surface, wherein the duct section comprises a first end with a male end portion configured to fit in a female end portion of one of the one or more other duct sections. The said female end portion comprises a receiving opening in a circumferential wall of 10 the female end portion. The male end portion comprises an opening in a circumferential wall of the male end portion, wherein said opening is spaced a first distance apart from the first end. The male end portion comprises a protruding member that is arranged to pass through the opening in the 15 male end portion projecting outwards with respect to the outer surface of the outer wall and, when interconnected with said one of the one or more other duct sections, passes through the receiving opening of the female end portion, and wherein said protruding member is supported by a resilient member 20 which is arranged inside the duct section.
