Abstract: A card connector for receiving a complementary card includes an elongate insulative housing having a first elongate wall, a second elongate wall opposite the first elongate wall and defining a plurality of passageways therein, a slot defined between the first and the second elongate walls and communicating with the passageways, and first and second supporting arms respectively and integrally formed with the two elongate walls and extending substantially perpendicular therefrom. A plurality of contacts are received in the passageways and project into the slot. First and second elastic locking members extend from two distal ends of the first elongate wall and are spaced from the first and second supporting arms for engagement with the complementary card which is inserted into the slot of the housing, wherein the locking members are manually bent outward with respect to an axis therebetween for releasing the engagement between the complementary card and the connector.
