A Tie bar (also Tie slide, Tie clip, or Tie clasp) is a neckwear accessory that clips a tie to the underlying shirt front, preventing it from swinging and ensuring the tie hangs straight, resulting in a neat, uniform appearance. Rising to prominence in the 1920s, the tie bar gradually replaced the tie pin.
Tie bars are usually made of metal and often have minor decorative patterns (see picture). Some tie bars have a small badge indicating membership to a club or an affiliation in the same way that ties themselves often have, or some other commemorative token. Occasionally, tie bars made of leather or chain are seen.
