Abstract: A connector adapted to receive a flat electrical conductor, such as a ribbon cable 4, has a lever 3 operable to open and close a conductor receiving opening. The rotative axis of the lever 3 is arranged to resist opening due to tugging of the cable 4 away from a mounting surface 49. The lever 3 is urged to its end positions by cooperation with an external fixing 21 of the connector; this allows a high biasing force without an excessive contact force between the cable 4 and terminals 2 of the connector.
