PROBLEM TO BE SOLVED: To simplify a structure by shortening the wiring of vibration sensors, confirming the closing of a window by an alarm device, and detecting and alarming abnormal vibration by the right and left vibration sensors. SOLUTION: In this locking device for the window locking left and right window frames 1, 2 by a crescent lock 4 installed at the mating part 3 of these both window frames 1, 2, the vibration sensors 7, 8 detecting the vibration of window panes 5, 6 are stuck on the window panes 5, 6 near the crescent lock 4. The alarm device 10 is installed in proximity to the crescent lock 4. When both window frames 1, 2 are set at the same closing positions, one terminal 12 of the vibration sensor 7 is continued with the alarm device 10. Since a crescent lever 11 is rotated to the closing position, the other terminal 13 is continued with the alarm device 10 to bring both vibration sensors 7, 8 in an alarm operation state.
