This utility model discloses a quick-locking device for preventing loosening of metal hose connections, including a hook, a buckle, a wire rope, a handle, a switch, a housing, a ratchet, and a pawl. The ratchet and pawl are located inside the housing. The handle is fixedly connected to the ratchet via a rotating shaft. The rotating shaft has a wire rope hole. The wire rope passes through the wire rope hole, with one end connected to the hook and the other end connected to the buckle. The switch is connected to the pawl. When the switch is rotated in a first direction, the pawl can engage with the ratchet for a limited position. When the switch is rotated in a second direction opposite to the first direction, the pawl can release from the ratchet engagement. This utility model simplifies the operation process for preventing loosening of metal hoses and equipment connections, reduces the workload of personnel, improves work efficiency, ensures the connection quality of metal hoses and equipment, and reduces potential risks during operation.
