ABSTRACT:
A blocking plug is reliably locked in position in an insertion hole in a waterproof stopper and prevented from slipping off. A rubber-made waterproof stopper is fitted in the rear of a waterproof connector housing with a plurality of terminal accommodating chambers formed therein, the waterproof stopper having insertion holes corresponding to the individual terminal accommodating chambers. A stopper cover of synthetic resin having throughholes corresponding to the individual insertion holes of the waterproof stopper is provided to cover the waterproof stopper. The stopper cover is in the rear surface formed with engagement portions each for engagement with a corresponding engagement portion formed at the rear of a blocking plug. When a blocking plug is thrusted into the holes of the stopper cover and the waterproof stopper corresponding to a terminal accommodating chamber not used to accommodate a terminal, the engagement portion of the blocking plug is engaged with the corresponding engagement portion in the rear surface of the stopper cover to lock the blocking plug in position.
