ABSTRACT:
A link assembly comprising a body and a closure. The body is generally c-shaped and includes two ends that confront each other in a spaced-apart relation. Each end of the body is provided with two or more external, helical thread sets that extend from each end towards the body. The closure includes a main section with first and second ends and a threaded interior surface that extends the length of the closure member. The treaded interior surface of the closure member engages and mates with each of the thread sets at the ends of the body. The closure is movable between a first or open position, which exposes a gap between the ends of the body, and a second or closed position that closes the gap between the ends of the body. Preferably, the closure member can be moved between the first and second positions in approximately five revolutions.
