JOINT CONNECTOR

PROBLEM TO BE SOLVED: To provide a joint connector with a constitution capable of reliably detecting a semi-insertion state of a female terminal.SOLUTION: A female housing 4 has: a terminal holding part 6 in which a female terminal 5 is inserted; and a locking rib 16 projecting in a lamination direction and entering into the terminal holding part 6 of the other adjacent female housing 4. While the plural female housings 4 are laminated, the locking rib 16 is configured so that its terminal comes into contact with the female terminal 5 incompletely inserted in the terminal holding part 6 of the other adjacent female housing 4. Then, while the plural female housings 4 are laminated, an extension line 20 in the lamination direction of the locking rib 16 is configured so as not to interfere with the female terminal completely inserted in the terminal holding part 6 of the other adjacent female housing 4.
