A spark leakage shutoff protective device for a plug includes an upright snapping lever, a leakage detection electromagnetic valve, a restoring member, and an upright support wall. The snapping lever is located between the restoring member and the leakage detection electromagnetic valve. Thus, the snapping lever is hidden in the restoring member to reduce the volume of the spark leakage shutoff protective device so that the spark leakage shutoff protective device occupies a smaller space in the plug. In addition, the snapping lever is supported by the support wall, so that the snapping lever is not easily deformed or worn out during a long-term utilization, thereby enhancing the lifetime of the snapping lever.
