A joint lock is a grappling technique involving manipulation of an opponent's joints in such a way that the joints reach their maximal degree of motion.
In judō these are referred to as, 関節技 kansetsu-waza, "joint locking technique") and in Chinese martial arts as chin na which literally means "catching and locking".
