A lever fitting-type connector includes a first connector on which a fitting detection member is slidably mounted a second connector, which is adapted to be fitted into the first connector, and a connecting lever which is provided on either one of the first and second connectors for operating the first and second connectors from a provisionally fitted condition to a completely fitted condition to each other. The fitting detection member slides to a lock position so that the fitting detection member is engaged with a first engagement hole of the connecting lever to lock the connecting lever in the completely fitted condition. When the fitting detection member is positioned at the lock position, a lock confirmation portion of the fitting detection member is projected from both of the first engagement hole and a distal end face of the connecting lever.
