As explained in detail above, when using the cap for preventing terminal disconnection of the present invention, when crimping the electric wire to the terminal, this cap is crimped and crimped at the same time as the electric wire to form an integral part with the terminal with electric wire. However, since it is possible to prevent the terminal from coming out of the housing with a single insertion operation of inserting it into the housing, work efficiency is greatly improved compared to conventional means. In addition, if the terminal is not inserted until it is locked in the locking lance of the housing, the cap will protrude from the rear end of the housing, making it easy to visually confirm whether the locking is completed or not. Confirmation becomes even easier if colored.
