A safety device includes a garment shaped to be worn on a torso of a user. A flexible strap is attachable to the garment and extends from the garment on first and second sides. The strap has first and second ends. An elongated first fastener component is attached at or near the first end of the strap. An elongated second fastener component is attached at or near the second end of the strap. The first and second fastener components can be rotated to be aligned with, or oblique to, the strap. The first and second fastener components are capable of locking engagement with each other, and are shaped for being used individually as anchors while separated from each other.
