A hooked spreader bar is held to a sailor's body by straps at each end. The straps are formed with serrations that are engaged by noses of pivotable locks. When the straps are tight, the locks prevent the straps loosening but provide a quick-release operation when pressed down. The spreader bar is more reliably held to a sailor's body, more simply fitted, and removed. Pivotable locking handles hold respective locks in the closed position.
