To provide a connector in which a lance beak part will not be broken, even though a large load is applied by a front holder. A locking lance is provided, at its distal end, with a lance beak pad which is adapted to be caught by a lock releasing jig for releasing lock of the locking lance with respect to a terminal, and a locking projection which is continued from the lance beak part and erected from a terminal end of the lance beak part. When a projected part is inserted into e deflection space in a state where the locking lance is deflected, a lower face of the projected part overrides an upper face of the lance beak part, and a distal end of the projected part comes into contact with a vertical face of the locking projection which is erected from the lance beak part.
