Baldric

A baldric or sash was a wide ornamental belt worn over one shoulder and around the waist.

Worf wore a baldric in top of his Starfleet uniform as a symbol of his Klingon heritage. In 2369 Worf's baldric was useful in locating him when he was involved in a shuttlecraft accident. The unique metals used in it's construction allowed it be more detectable in sensor scans.
