• the first bar is arranged to removably receive a karabiner-like snap-hook fixed to a first end of a first strand comprised in said timepiece or piece of jewelry,
• said snap-hook comprising, a hook including a curved beak portion arranged to enclose said first bar on part of its circumference, and a retaining latch which is elastic or elastically fixed to said hook and defines therewith an eyelet opening, and arranged to allow the insertion of said first bar into said eyelet of said snap-hook by pressure in a plane substantially perpendicular to the axis of said first bar, and to prevent the removal thereof from said snap-hook without user manipulation,
• wherein said first bar includes, at a distance from each of said first points of attachment to said structure, a notch having two sides arranged to limit the lateral travel of said curved beak portion, and to limit the angular travel of said snap-hook with respect to said first bar, in order to prevent any contact between said snap-hook and said first set of horns to which said first bar is fixed.
