Abstract
Joint portions to which tubes are coupled are provided with a pair of connector portions which are engaged/disengaged in accordance with the engagement/disengagement of the joint portions , respectively. Further, a detection circuit is provided which detects the non-conduction state between terminals B provided at the connector portions , respectively. The detection circuit is arranged to output an alarm signal when the state between the terminal metal members is non-conductive. Thus, when one of the joint portions disengages, the corresponding one of the connector portions also disengages, so that the state between the terminal metal members becomes non-conductive and the alarm signal is generated.
