Device for positioning and fixing wires in tubes

A flexible ring device for positioning and fixing solid and hollow wires in a tube, said flexible ring comprising:

• a convex outer surface and a concave inner surface, said surfaces being radially spaced apart as to define a radial direction thickness in the ring that provides for flexibility in said ring;
• a first edge and a second edge, said edges being spaced apart by a distance in an axial direction that is perpendicular to the radial direction as to define an axial length of said ring;
• a continuous slot in the ring extending axially from said first and second edges and radially from the concave inner surface to the convex outer surface of said ring such that the flexible ring is a non-closed annular element, the continuous slot providing for circumferential size adjustment in said ring upon compression or expansion of said ring as to enable, in use, a friction engagement clamping relationship between circumferentially spaced apart first and second portions of the convex outer surface of said ring and an interior surface of the tube, and said ring being configured such that, in use, there is further defined a wire reception recess formed between the interior surface of the tube and a third portion of the convex outer surface of said ring, which third portion extends circumferentially between said first and second portions, and said first, second and third portions of the convex outer surface being configured as to provide for position fixing of one or more solid or hollow wires received in the wire reception recess with respect to the interior surface of the tube.
