A joint connector has a housing (10) with cavities (11) capable of accommodating mating terminals (30) and a joint terminal (40) with a strip-like base (41) and terminal portions (42) projecting at specified intervals from the strip-like base (41). Insertion openings (18) are formed in a part of the housing (10) before the cavities (11) and communicate with the cavities (11). The joint terminal (40) is mounted into the housing (10) from the front with the terminal portions (42) in the lead. The strip-like base (41) has engaging holes (43) located between the terminal portions (42). Engaging projections (19A) project from a resilient wall (19) continuous with left and right side wall portions (12D) of the housing (10) and engage with the engaging holes (43).
