PURPOSE: A device for detecting the burst of a blast hose of a shot ball blaster is provided to enable a differential pressure sensor to detect the pressure gradient of a space and an air outlet. CONSTITUTION: A device for detecting the burst of a blast hose of a shot ball blaster comprises a cover member(90) and a differential pressure sensor(100). The cover member covers up a vent of a connecting member(10) and a space(91) of a connection part(P) of a blast hose(70). The differential pressure sensor senses the pressure gradient of the space located inside the cover member. The differential pressure sensor blocks the supply of the compressed air of a compressor(30) or the supply of the shot ball of a shot ball tank(50). An electronic valve(120) is formed between a shot ball inlet(130) of the connecting member and the shot ball tank. The electronic valve senses the pressure gradient of the space in which the differential pressure sensor is located inside the cover member. The electronic valve closes the shot ball inlet.
