Abstract: The invention relates to a transporting system for items of luggage, in particular to a so-called wheeled case or trolley with releasable or exchangeable case elements. The transporting system for items of luggage comprises a rolling mechanism (10) and at least one item of luggage or case element (20), the rolling mechanism (10) having a wheel arrangement (11), a pulling device (12) and fastening means (13) for releasably connecting the item of luggage (20) to the rolling mechanism, and is characterized in that the fastening means (13), on the one hand, are connected to the rolling mechanism and, on the other hand, can be fixed in a releasable manner in an interior of the item of luggage (20). The fastening means may comprise, for example, touch-and-close fastener strips (13) which can be introduced into the interior of the item of luggage through slots (22) made in a rear wall (21) of the item of luggage (20), and can be fixed there on a touch-and-close fastener strip.
