PROBLEM TO BE SOLVED: To provide a clear feeling of a locking click, even if an arm-like lock spring of mold plastic or the like is annealed, and to make it easy to see if lock is complete or incomplete. SOLUTION: A connector housing 110 for a cable-side connector 100 is provided with a locking projection 120. A connector housing 210 for a substrate-side connector 200 is provided with an integrally formed arm-like lock spring 220 and with one end thereof supported and fixed on the connector housing 220 and the other end in contact with a tip portion of the arm-like lock spring 220. There is provided a metal spring 230 for increasing the force with which the tip portion of the arm-like lock spring 220 is pressed against the locking projection and the periphery thereof on and after moving over the locking projection 120, when the lock spring is fit and locked.
