Abstract
A retaining pin with self biasing keeping means has a head and a tubular pin that has a plurality of detent fingers on its end. The detent fingers are formed by slitting and deforming the ends of the pin. The detent fingers are bent to extend beyond the outside diameter of the pin with the forward ends terminating in a diameter smaller than that diameter. As the pin is inserted in a matched opening, the detent fingers compress to allow the pin to penetrate the opening and then return to their original position to retain them therein. To remove the pin, the process is reversed. The instant retaining pin with self biasing keeping means is conducive to modern mass production methods of production such as cold heading.
