A tourniquet comprising:

• (A) a first strap, wherein the first strap is adapted for being positioned at least partially around a portion of the body of a person or animal;
• and
• (B) a twisting assembly, wherein the twisting assembly comprises:
• (1) a base part, wherein:
• (a) the base part is operatively held against twisting when the first strap is positioned at least partially around the portion of the body of the animal;
• and
• (b) the base part comprises a plurality of teeth arranged in a circle;
• and
• (2) a twisting part, wherein:
• (a) the twisting part comprises a plurality of teeth arranged in a circle, the teeth of the twisting part being adapted to move out of close engagement with the teeth of the base part to allow rotating in one rotational direction but when in close engagement with the teeth of the base part prevents rotation in the opposite rotational direction;
• and
• (b) the twisting part comprises a windlass portion, wherein the first strap is operatively connected to the windlass portion such that when the windlass portion is rotated, the first strap is twisted, whereby when the windlass portion is turned, the tourniquet is tightened around the portion of the body.
