clevis (KLEV-is) - n., a U-shaped coupling having holes at each end, through which a bolt is run.


The advantage of which is that whatever the bolt runs through has a certain amount of space to pivot in one direction while being restricted in others. Looks a lot like an old-fashioned type of shackle. Dates from the 1590s, of uncertain origin, though cleave is often suggested because of the fork of the U.
