A socket connector (100) includes an insulative housing (1) and a frame (3). The housing defines a mating interface (101), a mounting interface (102) opposite to the mating interface and periphery faces between the mating interface and the mounting interface. The frame has an opening (31) therein to accommodate the housing. At least one retaining device (11) includes a stopper portion (111) and a resilient claw portion (113) unitarily formed on the periphery face of the housing. One face of the frame is supported by the stopper portion and the opposite face is abutted against by the resilient claw potion while the housing is assembled in the opening of the frame.
