FIELD: jewelry industry. SUBSTANCE: folding fastener has at least one plate with pivotal joint for opening of bracelet. Said plate (plates) is manufactured from resilient deformable material providing mating of article and user's wrist form. Deformation of plates caused by force applied in direction perpendicular to plane of plate exceeds deformation of plates caused by the same force, but this force acts in any other direction. Plates are manufactured from composite material, for example, plates are composed of metal core covered with material tending to plastic deformation, such as rubber, plastic or leather. Folding fastener may be used in bracelet for watch. EFFECT: increased strength, wider range of use and simplified construction. 14 cl, 6 dwg
