ABSTRACT:
An easily assembled twin ear style key ring. The main body thereof is comprised of two casing halves, i.e., the front casing and the rear casing. A hollow stub on one of the casings extends through a hole provided on the other casing to quickly join the two casings together. The ends of the puller pins are inserted into positioning bushings having slightly larger diameters than the puller pins. The bushings are fixed in the main body by the front and the rear casings when the casings are pressed together. Manufacturing of the twin ear key rings is therefore faster than prior art devices, and is favorable to mass production.
