A board-mounted electrical connector makes it possible to sufficiently reduce stress in the connector housing caused by threaded attachment fixtures. Metal fixtures (30) for mounting of the electrical connector to a circuit board are arranged in end sections (27) of a thin and long housing (20). The metal fixtures (30) are secured in oblong openings (72) provided in end portions (46) of a metal shield (40) attached to an outside surface of the housing (20) so that they cannot rotate inside the openings. The metal fixtures (30) are retained in the openings by means of integral resilient retaining members (71) of the shield (40) being disposed in grooves (36) in the metal fixtures (30).
