Abstract: A holding tool (40) is inserted into a retainer-attaching hole or a holding tool-accommodating space (22) with the holding tool (40) supporting a short-circuit terminal (15) therein. The short-circuit terminal (15) is inserted into a cavity (14) in a connector housing (10) by pushing a rear end of the terminal (15) through a handling aperture (23) by means of a pushing pin (45). Since the terminal (15) is inserted into the connector housing (10) from its lower side, a front opening of the cavity (14) can be formed into the smallest size so that a short-circuit-releasing member (31) can enter the opening (20). Extraneous substances hardly enter the cavity (14) in the connector housing (10) through the opening (20). Also, since the handling aperture (23) may be formed into the smallest size so that the pushing pin (45) can enter the aperture (23), the connector housing (10) becomes a small size.
