ABSTRACT:
A safety shield for an electric plug includes a plate member adapted to be held secure against the base of the electric plug with the prongs of the plug extending through complementary openings in the plate member. The plate member carries rotatably a flexible cage member surrounding the prongs of the electric plug, and the cage member is collapsible. In this way as the prongs are inserted into the electric outlet, the cage will collapse to permit insertion, and as the plug is withdrawn from the electric outlet, the cage member will return to its original shape to guard against inadvertent contact with the electrical prongs. The cage member includes a bar element which in one position of the cage member will lie across the tips of the prongs to prevent insertion into an electric outlet, and the cage member can be rotated to position the bar element between the prongs of the plug to enable the plug to be inserted into an electric outlet.
