PROBLEM TO BE SOLVED: To provide the subject monitor working in such a way that conductors intended for guiding electric current to a pressure hose discontinue their activity when the pressure hose is broken, resulting in generating a signal by a loom control unit, and the signal acts so as to halt the loom, thereby preventing defective woven fabrics from being produced in large quantities. SOLUTION: This monitor works. as follows: conductors 8a, 8a' mounted on a pressure hose 8 and intended for guiding electric current to the pressure hose 8 discontinue their activity when the pressure hose 8 is broken, resulting in generating a signal by a loom control unit 9, and the signal acts so as o halt the loom; wherein it is preferable that the conductors 8a and 8a' of each of the pressure hoses 8 on a weft-inserting device 1 are mutually connected in such a conductor loop shape as to guide electric current at a hose joint position 10 of the weft-inserting device 1 and also mutually connected in such a conductor release loop shape at one end of the pressure hose 8; one of the conductors 8a is used for introducing electric current, while the other 8a' is connected to the signal input terminal of the loom control unit 9.
