Abstract: A coupling member inhibits accidental pivoting of a lever for operating a movable member such as a chuck member or a valve. The coupling member has a chuck member mounted displaceably relative to a female coupling body between a temporarily connecting position (first position) and a connecting position (second position). The chuck member is operated by a lever that is pivotable relative to the female coupling body. When the lever is pivoted from a first pivoting position to a second pivoting position, the chuck member is displaced from the temporarily connecting position to the connecting position to connect an associated male coupling member. When the lever is in the second pivoting position, a lock member of the lever engages a lever holding member to inhibit the lever from pivoting toward the first pivoting position.
