Body belt
A body belt is any waist belt which has D-rings or other attachment points. The belts can be used as medical restraints in institutions for bed and wheelchair restraints, and for safety in activities such as abseiling or construction work. When they are used in sexual bondage plays they are commonly referred to as bondage belts, and also worn in fetish clothing. The belts are usually fastened with buckles and some by a locking mechanism, which enables quick release.
Use in sexual bondage
For sexual bondage plays a body belt is usually called a bondage belt. Though it is not a physical restraint by itself, it can be used to provide an anchoring point for other restraints, such as bondage cuffs, rope, etc. Lengths of simple leather strapping with buckles are sometimes also referred to as bondage belts, because they can be used quickly to bind limbs.
Most bondage belts are made of fabric or leather as these materials tend to be more comfortable and better distribute pressure over the skin.
