Claim:
A connector, comprising: a first housing, provided with a projection; a second housing, provided with a retainer which is operable to engage the projection of the first housing; an engagement detector, held in the second housing and slidable between a first position and a second position; and a lock canceller, which is operable to disengage the retainer from the projection only when the engagement detector is placed at the first position, wherein: the retainer prevents the engagement detector from sliding from the first position to the second position except when the projection and the retainer are completely engaged with each other at a complete engagement position; the engagement detector locks the retainer at the complete engagement position when the engagement detector is placed at the second position; and the engagement detector and the retainer are moved to a third position at which the engagement detector is allowed to be forcibly moved to the first position, in a case where the lock canceller is manipulated when the engagement detector is placed at the second position; wherein the engagement detector includes a detection hook, and the engagement detector is placed above the lock canceller.
