A safety socket protective cover includes an outer housing, an inner housing, a sliding cover, an elastic support member and an elastic member. The sliding cover, the elastic support member and the elastic member are disposed at a gap between the outer housing and the inner housing. The sliding cover is provided with wedge members for corresponding with receptacles at the outer housing, wherein each wedge member has a passive inclined plane. The elastic support member has elastic restoring forces and is disposed below the sliding cover. The elastic member is pressed between the sliding cover and the outer housing. When the sliding cover receives abnormal forces, the wedge members block the receptacles at the outer housing due to unequal forces received, thereby preventing alien objects from entering the receptacles.
