A card edge connector (100) includes an insulative housing (1) and a latch retained at one end of the insulative housing (1). The insulative housing (1) includes a mounting slot (16). The latch (3) has a resilience extending portion (311) retained in the mounting slot (16) upwardly. The mounting slot (16) defines a pressing face (112) latching with the extending portion (311) for preventing the extending portion (311) from moving downwardly, thereby the latch (3) could be stably retained on the housing.
