A connector is provided to detect partial mounting of a retainer. A female housing 11 of the connector 10 is provided with an escaping portion 20, which is aligned with a lock arm 14 in its deforming direction only when a retainer 15 is mounted in a full locking position. By being aligned with the escaping portion 20, the lock arm 14 is enabled to undergo an elastic deformation to permit the connection of the female housing 11 with a male housing 12. On the other hand, if the retainer 15 is partly mounted without reaching the full locking position, the escaping portion 20 is not aligned with the lock arm 14, which refrains the lock arm 14 from being sufficiently elastically deformed. As a result, the female and males housings 11, 12 cannot be connected, which enables detection of partial mounting of the retainer 15. Thus, partial mounting of the retainer 15 can be securely detected by setting a degree of deformation of the lock arm 14 larger than a clearance between the housings 11 and 12.
