Abstract
A bracelet including flexible end parts arranged to overlap each other in the closed position of the bracelet. The bracelet includes a first magnetic circuit portion integrated in one of the end parts and a second magnetic circuit portion integrated in the other end part, the magnetic circuit portions being arranged to mutually attract each other to unite the two end parts in the closed position of the bracelet. One end part includes second magnetic circuit portions which are arranged parallel to each other and spaced apart from each other to enable the length to be selected. The magnetic circuit portions include a soft ferromagnetic alloy yoke arranged transversely to the bracelet and parallel to the surface of the end part in which the magnetic circuit portion is integrated. The first magnetic circuit portion includes bipolar magnets arranged between the yoke and the contact surface of the end part.
