A card edge connector includes an insulative elongated housing defining an elongated slot extending along a longitudinal direction. Two rows of contacts are disposed in the housing so as to be paired in each cross-sectional plane in a transverse direction. A pair of towers are located at two opposite ends of the housing in the longitudinal direction. A pair of ejectors/lockers are disposed in the corresponding towers and rotational about a pivot extending along the transverse direction. Each ejector has a bottom kicker adapted to intimately confront a bottom edge of the memory module for ejecting the memory module out of the housing. The kicker slightly interferes with the contacting sections of the neighboring contacts when the ejector is located at an outer position so as to be retained in position with regard to the housing.
