A connector has a male connecting member and a female connecting member. A monitor element comprising a resistor and a switch which are connected in series is provided in the male connecting member. The switch is provided to be opened when the connector is in a completely connected state. A monitoring circuit including the monitor element having a pair of output terminals at ends of the circuit is provided for detecting voltage across the output terminal. A change of the voltage upon the disconnection of the connector is signaled.
