A coupling system provides a media-conducting connection of two hose-shaped sections (10, 12). Each section has one coupling element (16, 18), with two coupling parts (20, 22) that can be separated from each other and that are detachably held to each other by closure elements (24) along a disconnecting point (26). The closure parts of one coupling element can be engaged with correspondingly designed closure elements (24) of the other coupling element (20, 22) to form the transport section. All closure elements (24) of the coupling parts (20, 22) point hose-inward, at least before forming the transport section. Upon producing the transport section, the respective disconnecting point (26) is arranged between the coupling elements (16, 18), transversely to the transport section.
