An expansible finger ring comprises a male hoop part 1 and a female hoop part 2 hinged together at 3. The hoop parts can be locked together to close the ring by interengaging the distal end 6 of a tongue 4 on the male hoop part in a recess 5 in the female hoop part. Unlocking the hoop parts to open the ring is effected by finger nail pressure applied to a narrowing gap formed between a shoulder (10) on the male hoop part and a confronting end of the female hoop part. <IMAGE> |
