Abstract: Cables supporting and actually limiting excursion of a flexible thin-walled tube are held in position by spacers which are formed with recesses to receive the cables. To permit easy assembly, and eliminate threading the cables on the spacers with the hose in position, the spacers are formed as half-ring elements, coupled together independently of the cables which pass through recesses. The recesses may be tangentially or radially open slits so that the half elements can be slipped over a subassembly of hose and cables, or the recesses can be formed adjacent overlapping or abutting end portions of the half elements. The recesses also may be in the form of through-bores, on which half elements are threaded, the half elements then being fitted against each other around the hose. The half elements are held together either by external rings, interlocked with the half elements, or by overlapping regions, connected together by hook-and-recess connections, welding, adhesive or the like.
