An electrical socket connector adapted for mounting an integrated circuit (IC) module having a plurality of pins to a printed circuit board (PCB) comprising:

• a base having a plurality of contact passageways defined from an upper surface to a bottom surface thereof and at least a first protruding portion on one side thereof, the first protruding portion having a first receiving slot defined therein;
• a plurality of contacts received in the passageways of the base;
• a cover moveably mounted on the upper surface of the base and defining a plurality of receiving holes in alignment with the contact passageways adapted to receive corresponding pins of the IC module to extend therethrough into the passageways;
• and
• a locker means comprising a stopper portion and a locker portion extending from the stopper portion, the stopper portion abutting against one side of the cover near the first protruding portion, the locker portion comprising an extending portion perpendicular to the stopper portion, a holder portion downward extending from the extending portion, and a pair of side portions formed at a joint of the extending portion and the holder portion and parallel to the stopper portion, the locker portion received in the receiving slot of the first protruding portion and engaging with the first protruding portion thereby preventing the cover from moving on the base.
