A connector assembly according to the present disclosure includes a connector body, a lock reinforcement, and a secondary lock. The connector body has a plurality of terminal cavities and a plurality of lock projections configured to engage a plurality of terminals to retain the terminals in the terminal cavities. The lock reinforcement is slidable relative to the connector body for engagement with a subset of the lock projections to maintain the lock projections engaged with a first subset of the terminals. The secondary lock is slidable relative to the connector body for engagement with a second subset of the terminals to retain the terminals in the terminal cavities independent from the lock projections. The secondary lock is coupled to the lock reinforcement such that moving one of the lock reinforcement and the secondary lock moves the other one of the lock reinforcement and the secondary lock.
