Usually a U-shaped piece of iron or steel with holes at each end so that a pin could go through them. A clevis was used to connect two items, one with a ring at the end, and one that would fit in the U and had a hole in it for the pin to go through. There were also a variety of special-purpose clevises like the cross-link clevis shown on the right of the illustration. See also Plow clevis.
