摘要： A key ring 10 formed from a continuous piece of pliant spring wire 10 in a first unstressed configuration which comprises a large outer loop 14 having a free end portion 18 adapted to receive keys thereon. The unstressed configuration of the wire includes a smaller inner loop 16 of a size sufficient to receive one's finger therethrough and which loop 16 provides a first arcuate portion 20 in overlying relation to said free end portion 18 along its length. A second arcuate portion 22 extends from the inner loop and overlies the inner surface of the first arcuate 20 portion of the inner loop and provides therewith an external groove 24 adapted to receive the free end portion 18 of the outer loop which is easily manipulatable by one's fingers to be seated in the groove 24 and thereby place the key ring in a locked condition for retaining keys on the key ring. The free end portion 18 of the outer loop is also releasable from the locking groove 24 by use of one's fingers to squeeze the inner loop 16 towards a coaxial relation with the outer loop 14, whereby the free end portion snaps back to its original position and the key ring is returned to its unstressed configuration suitable for removal or placement of keys.
