A connector housing has a terminal insertion opening (32) formed on a front wall (30) of a cavity (23) formed in a tower part (21). A tapered guide surface (33) is formed on a front peripheral edge of the terminal insertion opening (32). An open groove (35) is formed forward of the lance (27) on a lower portion of the peripheral edge of the terminal insertion opening (32). A retainer (40) for unremovably doubly locking a female terminal can be mounted in the tower part (21). An auxiliary plate (60) projects from a lower portion of a peripheral edge of each window hole (43) of the retainer (40). A supplementary tapered guide surface (33A) is formed on a surface of an upper end of the auxiliary plate (60). A jig insertion hole (64) is formed on the auxiliary plate (60). When the retainer (40) is mounted in a main locking position, the auxiliary plate (60) fits into a cut-off portion of the peripheral edge of the terminal insertion opening (32). Thus, substantially all the peripheral edge of the terminal insertion opening (32) is surrounded with the guide surfaces (33) and (33A).
