ABSTRACT:
A connector is provided to improve the reliability of a primary locking function by an elastic lock piece without deteriorating a secondary locking function and an insufficient insertion detecting function of a retainer. When female terminals (20) are properly inserted, a retainer (30) can be pushed to its fully fitted state or full lock position since elastic lock pieces (14) are not located in deformation permitting spaces (15). When there is/are insufficiently inserted terminal(s) (20), the retainer (30) cannot be pushed to its fully fitted state or full lock position since it comes into contact with the elastic lock pieces (14) in the spaces (15). Since a lock projection and the elastic lock piece (14) are locked outside the terminal (20), a large engaging space of the lock projection (23) with the elastic lock piece (14) can be ensured without restricting a projecting amount of the lock projections (23) by the internal construction of the terminals (20).
