PROBLEM TO BE SOLVED: To prevent installation of both connector housings on a panel in a half fitting state. SOLUTION: A lever 30 forms an interference part 35 noninterfering with the hole edge of an installing hole H in a process of installing both connector housings 10 and 20 in the installing hole H in a normal fitting state, and interfering with the hole edge of the installing hole H in a process of installing both connector housings 10 and 20 in the installing hole H still in the half fitting state. A fitting state of both connector housings 10 and 20 can be detected by whether or not the interference part 35 interferes with the hole edge of the installing hole H in a process of installing both connector housings 10 and 20 in the installing hole H to prevent both connector housings 10 and 20 from being installed in the installing hole H still in the half fitting state.
