A stacked card-edge connector is provided for fixing and electrically connecting at least one electronic card to a circuit board. The stacked card-edge connector includes two stackable and interchangeable insulating housings, a pair of first card latches, a pair of second card latches, a pair of fasteners. The pair of first card latches are mounted respectively at the two sides of one insulating housing for fixing and/or holding the at least one electronic card. The pair of second card latches are secured respectively at the two sides of the other insulating housing for fixing and/or holding another electronic card. When two electronic cards are secured respectively by the pair of first and second card latches, disengagement of the electronic card secured by pair of first card latches causes a simultaneous disengagement of the electronic card secured by the pair of second card latches.
