The support, made from an extruded or molded synthetic material, consists of an inverted V-section strip, shaped to fit inside the hooks under tension. One edge (12) of the strip is notched to receive the main sections (2) of the hooks, while the opposite edge (21) is turned at an angle to receive the flat ends of the hooks and has a recess (15) to receive a bend (8) in the hooks.
