An article, such as a ring structure for example, having a band and an ornamental portion affixed on the top thereof. The band is formed of two portions each being pivotally hinged with respect to one another. One end of the portion of the band is provided with a wedge shaped resilient locking member which cooperates with a lock formed in a space formed between an upper surface of the band and the ornamental portion of the ring. For opening the ring from the closed to the open position, the user inserts a key in a keyway formed in the hollow space, whereby the key causes the locking member to be released from the lock and in turn as a rotational force applied the key upon the locking member, the band portion will be caused to pivot about the pivot point thus opening the ring band permitting release from the finger. Alternate embodiments include a locking arrangement without the hinge assembly.
