Abstract
A fluid connector fitting nut lock includes a sleeve that fits down over the nut and that has an integral locking mechanism to fix the sleeve in a raised position that allows the nut to be turned and in a locked position that prevents the nut from backing off due to vibration or other external forces. The integral locking mechanism eliminates the need for a separate lockwire or clipwire.
