Abstract: A ring of the type intended to be arranged on a body part of a wearer includes two rigid bent arms (10, 12) and an articulation (14) connecting them. The arms are mobile facing each other at the first (10a, 12a) of their two ends. A head part (16) is arranged in proximity to the articulation (14) and is arranged so as to be able to occupy a first position, called the locking position, and a second position, called the unlocking position. First and second connecting devices secure the head part respectively to the first and second arms. These locking devices are both locked when the head part (16) is in the locked position. At least the first of the locking devices is disengaged when the head part is in the unlocked position.
