Abstract: There is provided a device for carrying flexible cables or pipes from a fixed connection point to a mobile consumer. The device consists of a flexible support tube which may be either formed from a profiled strip would on itself with intermeshing edges, or a corrugated tube. In order to limit the flexibility of the tube to one direction, there are provided a series of spacers keeping a longitudinally continuous zone of the tube at a substantially constant length. The tube can thus only bend by compression or extension of the zone immediately opposite the zone of constant length. The spacers may take various forms such as a continuous strip secured to one surface of the tube, or a series of individual spacers entering formations in the tube. The individual spacers may in fact be individually secured to the tube or they may be carried on a strip.
