- (a) a base portion being elongated in length relative to the width of the base portion, the base portion having an upper surface and a lower surface;
(b) a first extension at one end of the base portion;
(c) means for providing a hinged connection between the first extension and the base portion;
(d) the first extension being thicker than the base portion, with a part of the first extension being normally below the lower surface of the base portion when the safety pin is in an open position;
(e) the first extension having a pin portion anchored therein, the pin portion extending substantially in a linear direction away from the first extension and the base portion when the safety pin is in an open position;
(f) the pin portion being readily biased back over the upper surface of the base portion by means of the hinged connection between the first extension and the base portion;
(g) a second extension comprising a detent extending in a reverse loop from the opposite end of the base portion for retaining the pin portion in a closed position when the pin portion is moved beneath the detent;

Abstract
A molded safety pin having an elongated base portion with extensions at both ends is described. At the first extension a hinged connection provides the means for biasing the pin portion at the juncture of the means for anchoring the pin and the base portion. At the second extension a detent structure provides the means for holding the pin portion securely when the safety pin is in a closed position while permitting convenient manual release of the pin when required.
Additionally a simplified injection mold for fabricating the safety pin is described.
