Which clamp, and how many? For a 2 to 5 mm cable, use the 6.5 mm clamp: 3 per joint, spaced 6 to 8 cable diameters apart. The pack of 10 covers 3 joints; the box of 100 is for a hop yard or a long fence.
Wire rope clip or plastic cable tie? This U-bolt clip (malleable steel body, steel bolt, zinc-plated) locks a loop of steel wire rope under tension: hop yard, fence, guy wires. It does not replace a plastic cable tie, which bundles electrical wires.
