<p>An object of the present invention is to prevent damage of a terminal fitting by an unlocking jig. A housing 10 is formed with jig insertion holes 20 penetrating through an outer wall portion 19 located at a side of deformation spaces 17 opposite to locking lances 14. Deformation restricting portions 42 of a front retainer 40 are formed with guide portions 49 which are so cut out as to allow an unlocking jig inserted through the jig insertion hole 20 to reach the locking lance 14 with the front retainer 40 located at a retracted position and position the unlocking jig in a width direction crossing both a resiliently deforming direction of the locking lances 14 and an inserting direction of terminal fittings 30 into cavities 13.</p>
