A joint connector has a housing (1) with cavities (3) into which female terminal fittings (2) are insertable, and a busbar (5) to be mounted in the housing (1). The busbar (5) has tabs (6) to be connected to the respective female terminal fittings (2) and adapted to short the female terminal fittings (2) to each other. The busbar (5) includes a base (15) used to mount the busbar (5) into the housing (1) and the tabs (6) are cantilevered from the base (15). The base (15) includes resilient legs (17) for allowing displacements of the tabs (6) in a direction crossing a longitudinal direction of the tabs (6). The tabs (6) can be displaced by displacements of the resilient legs (17) to absorb a misalignment between the tab pieces (6) and the female terminal fittings (2).
