A tourniquet assembly includes a strap and a windlass crank attached to a windlass cord that forms a loop that is slidably engaged with anchors that are attached to the main strap. During use, the crank is rotated, causing the windlass cord to twist. This effectively shortens the length of the windlass cord which also pulls the anchors inwardly, thereby causing a similar shortening of the main strap between the anchors and enabling the strap to be used for use as a tourniquet.
