A power outlet socket safety shield device comprises a left slider comprising a left transverse baffle and a left inclined stopper. A right slider comprises a right transverse baffle and a right inclined stopper. At least one elastic element is positioned between the left slider and the right slider. The left inclined stopper is inclined in a direction opposite to the inclination of the right inclined stopper. When the device is in a rest state, the left inclined stopper is above the right transverse baffle and the right inclined stopper is above the left transverse baffle. When the device is in an active state, the elastic element is compressed, the left slider and the right slider are moved in opposite directions to displace the left inclined stopper away from the right transverse baffle and to displace the right inclined stopper away from the left transverse baffle.
