Abstract: The invention relates to a device for holding lines in an aircraft that comprising at least one line inlet, at least one line outlet and at least one holding space for holding at least part of a line section extending between the line inlet and the line outlet, wherein the line section has a length that is equal to or greater than the clear distance between the relevant line inlet and line outlet, and wherein the holding space comprising means for separably holding, as well as for shortening or lengthening in a reversibly guided fashion, a line end that protrudes from the line inlet and/or line outlet. Due to the devices according to the invention, lines that are individually cut to length are no longer required for connecting reconfigurable rows of passenger seats because the device according to the invention releases or takes up excess line lengths depending on the position of the rows of passenger seats.
