A secondary terminal lock assembly for preventing the removal of an electrical terminal from a terminal block. The lock assembly includes a lock element which is inserted into a terminal block cavity adjacent a conventional female spring locked terminal. The lock element includes a notched locking tongue which engages a locking ear of the terminal block cavity and is held into engagement with the ear by the terminal spring. Shoulders on the locking element prevent withdrawal of the terminal from the terminal cavity. The locking element when properly seated can be seen from the plug side of the terminal block and thus provides a visible indication that the terminal is in a locked condition.
