A joint connector (10) for electrically connecting a plurality of terminal fittings (20) mounted on ends of a plurality of ground wires (W) of a vehicle includes a pair of terminal holding portions (49A, 49A) for holding a pair of the terminal fittings (20, 20). A pair of locking lances (43, 43) deflectable with respect to each other and configured to suppress the withdrawal of the pair of terminal fittings (20, 20) by locking the pair of terminal fittings (20, 20) are arranged back to back with each other via a deflection permitting space (44) between the pair of terminal holding portions (49A, 49A).

1. A joint connector for electrically connecting a plurality of terminal fittings mounted on ends of a plurality of wires of a vehicle, comprising: a housing having opposite front and rear ends and a plurality of pairs of terminal accommodating chambers extending through the housing from the rear end to the front end, the terminal accommodating chambers in each of the pairs being opposed to one another and the pairs of terminal accommodating chambers being arranged side by side to define two rows of terminal accommodating chambers, each of the terminal accommodating chambers being configured for holding one of the terminal fittings;a conductive member having a U-shaped tab coupling portion insert molded into the front end of the housing, tabs extending from the tab coupling portion and projecting into the respective terminal accommodating chambers for contacting the terminal fittings held therein, and a mounting portion extending from the tab coupling portion to a location external of the front end of the housing, the mounting portion being configured for mounting to and grounded by a body of the vehicle;pairs of locking lances cantilevered forward in the housing and disposed so that the locking lances in each of the pairs of locking lances project partly into the terminal accommodating chambers in each of the pairs of terminal accommodating chambers, the locking lances being deflectable with respect to each other and configured to suppress withdrawal of the terminal fittings by locking the terminal fittings, the locking lances in each of the pairs of locking lances being arranged back to back with each other and on opposite sides of a forwardly open deflection permitting space between the terminal accommodating chambers in each of the pairs of terminal accommodating chambers; andforwardly open lateral communication spaces between the deflection permitting spaces. 2. The joint connector of claim 1, wherein the communication spaces extend from the front end of the housing to locations in the housing from which the locking lances are cantilevered. 3. The joint connector of claim 1, further comprising an inspection member for inspecting a locking state of the locking lances, the inspection member being insertable into the communication spaces and the deflection permitting spaces. 4. The joint connector of claim 1, wherein: the terminal accommodating chambers in each of the pairs of terminal accommodating chambers are arranged in parallel. 5. The joint connector of claim 1, further comprising a guide portion formed in the housing and configured to guide a lateral edge part of the inspection member extending in an inserting direction. 6. The joint connector of claim 1, further comprising forwardly open inter-chamber communication spaces between the locking lances that are laterally adjacent to one another. 7. The joint connector of claim 1, wherein a dimension of each of the deflection permitting spaces in a direction parallel to a deflection direction of the respective locking lances being sufficiently large to permit one of the locking lances in the respective pair of locking lances to be deflected sufficiently for one of the terminal fittings to be inserted into or removed from the corresponding terminal accommodating chamber, but being too small to permit both of the locking lances to be simultaneously inserted into or removed from the terminal accommodating chambers of the respective pair. 8. A joint connector for electrically connecting a plurality of terminal fittings mounted on ends of a plurality of wires of a vehicle, comprising: a housing having opposite front and rear ends and a plurality of pairs of terminal accommodating chambers extending through the housing from the rear end to the front end, the terminal accommodating chambers in each of the pairs being opposed to one another and the pairs of terminal accommodating chambers being arranged side by side, each of the terminal accommodating chambers being configured for holding one of the terminal fittings;pairs of locking lances cantilevered forward in the housing and disposed so that the locking lances in each of the pairs of locking lances project partly into the terminal accommodating chambers in each of the pairs of terminal accommodating chambers, the locking lances being deflectable with respect to each other and configured to suppress withdrawal of the terminal fittings by locking the terminal fittings, the locking lances in each of the pairs of locking lances being arranged back to back with each other and on opposite sides of a forwardly open deflection permitting space between the terminal accommodating chambers in each of the pairs of terminal accommodating chambers;forwardly open lateral communication spaces being between the deflection permitting spaces; anda breaking groove provided on an outer peripheral surface of the housing and extending circumferentially around the outer peripheral surface of the housing in a direction transverse to a direction extending from the front end to the rear end to permit breaking of the housing for removing the terminal fittings and the wires connected thereto. 9. The joint connector of claim 8, wherein the wires are ground wires and a conductive member electrically connected to the plurality of terminal fittings is mounted on and grounded to a vehicle body. 10. The joint connector of claim 8, wherein the breaking groove is at a position in a front-back direction substantially aligned with rear end parts of the deflection permitting spaces and with the lateral communication spaces between the deflection permitting spaces. 11. A joint connector for electrically connecting a plurality of terminal fittings mounted on ends of a plurality of wires of a vehicle, comprising: a housing having opposite front and rear ends and a plurality of pairs of terminal accommodating chambers extending through the housing from the rear end to the front end, the terminal accommodating chambers in each of the pairs being opposed to one another and the pairs of terminal accommodating chambers being arranged side by side, each of the terminal accommodating chambers being configured for holding one of the terminal fittings;pairs of locking lances cantilevered forward in the housing and disposed so that the locking lances in each of the pairs of locking lances project partly into the terminal accommodating chambers in each of the pairs of terminal accommodating chambers, the locking lances being deflectable with respect to each other and configured to suppress withdrawal of the terminal fittings by locking the terminal fittings, the locking lances in each of the pairs of locking lances being arranged back to back with each other and on opposite sides of a forwardly open deflection permitting space between the terminal accommodating chambers in each of the pairs of terminal accommodating chambers, a dimension of each of the deflection permitting spaces in a direction parallel to a deflection direction of the respective locking lances being sufficiently large to permit one of the locking lances in the respective pair of locking lances to be deflected sufficiently for one of the terminal fittings to be inserted into or removed from the corresponding terminal accommodating chamber, but being too small to permit both of the locking lances to be simultaneously inserted into or removed from the terminal accommodating chambers of the respective pair; andforwardly open lateral communication spaces between the deflection permitting spaces.
