To provide a connector locking detection device which facilitates confirmation of locking in operation for connecting automatic connectors, and has heat resistance so that it can be used even in a rail road vehicle for transporting molten steel.
The connector locking detection device includes: a magnet 26 interlocking with a lock 5 of the automatic connector 1; a magnetic sensor 23 which faces the magnet 26 when the lock 5 is in a locking position, and is disposed in a separation position from the magnet 26 in an opposite position to the locking position to convert a magnetic field of the magnet 26 into an electric signal; a wireless tag 24 which has a magnetism detection means for detecting the magnetic field of the magnet 26 by the magnetic sensor 23 and outputting a magnetism detection signal indicating the existence of magnetic field detection, and a wireless transmission means for wirelessly transmitting the magnetism detection signal; a metal mounting pedestal 21 which secures the magnet sensor 23 and the wireless tag 24 to a connector body; and a heat-resistant/heat-insulating sheet 25 which covers the magnetic sensor 23 and the wireless tag 24.
