ABSTRACT:
The present invention is intended to provide an apparatus capable of detecting an air tube-detached state when said air tube has been detached from an air-actuated valve in order that the same air-actuated valve is caused to assume a closed state. The present invention relates to an air tube connection state detecting apparatus 10 for detecting whether the fore end of an air tube 56 for supplying compressed air to an air-actuated valve 16 for a gas container 12 is connected to said air-actuated valve 16 or not. The air tube connection state detecting apparatus comprises a to-be-contacted member 82, provided at a predetermined position separate from said air-actuated valve 16, to which the fore end of said air tube 56 is to be connected; and a detection means 86 for detecting that the fore end of said air tube 56 is connected to said to-be-connected member 82. If it is detected by the detection means 86 that the air tube 56 is connected to the to-be-connected member 82, in this construction, it can be recognized that the air tube 56 has been detached from the air actuated valve 16.
