the.com/bolo tie

means A string necktie held together by a decorative clasp or slide, often cinched with metal tips, worn instead of a knotted tie.

from The name comes from 'boleadora,' the leather-thonged throwing weapon used by South American gauchos to snare cattle — likely the inspiration for the cord-and-clasp design that emerged in the American Southwest in the 20th century. Southwestern silversmiths, often credited to Arizona in the 1940s, popularized the style, and it was later named the official state neckwear of Arizona and New Mexico.
