Abstract: The invention provides an electrical connector to which a metal latch can be easily attached. An attachment post (16a) mounted on an upper surface (18) of a housing (12) has a main wall (16b) and an outer side wall (30) opposed thereto. A front side wall (28), perpendicular to the main wall, is located at a front end of the main wall (16b). A central portion of the main wall (16b) has a rectangular engaging projection (40). A rear end of the main wall (16b) has a rear side wall (42) projecting outward to face the front side wall (28). A slot (46), having a rectangular cross section and defined by the main wall (16b), the outer side wall (30), the front side wall (28) and the rear side wall (42), is produced on the attachment post (16a). A base portion (62) of the metal latch (60), which is to be inserted in the slot (46), has forked portions (64) and (66) extending downward.
