A latch member (52) for coupling a connector (48) and header (44) together to provide an electrical connector assembly. The latch member (52) comprises an elongated member (60) having a first end (62) and a second end (64). A fastening segment (68), which can securely engage an outer wall of a header to assist in securing the latch member in an operating position, is intergrally coupled near the second end. At least one latch element, adapted to securely engage and immobilize the connector element in cooperation with the header, is integrally coupled near the first end. The latch member also functions as an electrical shield for the header and the mating connector.
