This invention aims to provide a joint connector which makes it easy to insert a tool therein upon detaching a female terminal therefrom and prevents a locking finger from being deformed and impacted. A locking finger (1d) is arranged inwardly below an outer face of a side wall (1b) of a connector housing (1). The side wall (1b) is provided on an outer face with an outwardly slanted portion (1h) which inclines and extends outwardly from an end face (1e) opposite to a distal end of the locking finger to the outer face. The slanted portion (1h) guides a tool (5) to insert it into the connector housing (1). An upper end of the slanted portion (1h) becomes a fulcrum for the tool and thus a distance between the fulcrum and an acting point of the tool becomes longer. In order to prevent a short-circuit due to a leak between branched circuits, a coupling portion (25a) of a shorting plate (60) abuts on a distal end of a side wall (12) of the connector housing (1) so that the distal end limit an insertion position of the shorting plate (60). The connector housing (1) includes first side walls (12a, 12b, 12d) the distal ends of which abut on the coupling portions (25a) of the shorting plates (60A, 60B) for a divisional shorting use and a second side wall (12c) the distal end of which abuts on the coupling portion (25a) of the shorting plate (60) for an all pole shorting use. In order to avoid interference upon connecting alternately electrical wires directed in opposite directions, a joint chamber (115) is provided between piled terminal accommodating chambers (13), which are communicated with the joint chamber through apertures (112). The shorting plate (60) is inserted into the joint chamber (115) to confront a given aperture (112). A female terminal (2) is provided with a tongue piece (22c) which elastically contacts with the shorting plate (60) through the aperture (112). When the terminal (2) is inserted to the terminal accommodating chambers (13) having openings (131) directed alternately in the reversed directions, the tongue piece (22c) contacts with the shorting plate (60) to electrically interconnect them. Since the chamber (13) may be arranged through the aperture (112) adjacent to the joint chamber (115), the chamber can be directed in any direction. In order to use electrical wires having different diameters, the connector housing (1) is provided with terminal accommodating chambers (13) having different sizes so that the housing can simultaneously accommodate electrical wires (91 and 92) with large and small diameters. Since a contacting portion (22) of each terminal (2) has a common shape, the chamber (13) can accommodate either large or small diameter wires.
