A Hula Hoop
"A looped piece of wire rigging that is fitted with a swaged metal clamp and used as a sling which would usually be put over a fitting such as a TIMBERHEAD. Then a RATCHET with one end already attached to the eye splice in a barge wire would have its other end engaged in the hula hoop. Most times the hoop has a set of chain links attached in it. The name comes from the appearance of a child's hula hoop when new, before it is pulled out of shape under the stress that is placed on rigging."
