Abstract
Connectors (33, 45, 52) are connected to each other when joints (15) that connect tubes (14) and pipes (20, 40) to each other are mounted thereon. The connectors (33, 45, 52) are disconnected from each other when the joints (15) are removed therefrom. A detection circuit (8) detects an electrical disconnection between terminals (70) and (33) in the connectors (52) and (33B), respectively and outputs an alarm signal to inform an operator that the joint (15) has not been installed on the tube (14) or the pipe (20, 40).
