A cell-monitoring connector is configured to be detachably mounted to a fuel cell. A housing configured such that a portion thereof is insertable into a receiving space. A pair of lever operators is configured to be movable by a first external pressure in a third direction that intersects the first direction and the second direction. A number of levers are coupled to the pair of lever operators inside the housing. The levers include latching protrusions configured to operate in connection with movement of the lever operators. The latching protrusions are movable between a first position at which the latching protrusions protrude in the third direction from an outer surface of the housing and a second position at which the latching protrusions do not protrude from the outer surface of the housing.
