A retractable sensing assembly having a housing, a sensor connectable to an article to be monitored, a conductive element operatively connected to the sensor and a mechanical cable. The sensor has a secured state and an unsecured state. The conductive element is selectively extendable from and retractable into the housing. The conductive element includes at least one conductive wire through which the state of the sensor can be detected. The mechanical cable is connected to the sensor and is connectable at an anchoring location so that movement of the sensor is confined by the mechanical cable relative to an anchoring location to which the mechanical cable is connected.
