Abstract
Assembly element made in a plate of brittle material, such as silicon, in particular for a timepiece, including an aperture provided for the axial insertion of an arbour, the inner wall of the aperture including elastic structures which are etched into the plate and which each include at least one support surface for gripping the arbour radially in order to secure the assembly element relative to the arbour. Each elastic structure is formed by a fork which is connected to the inner wall of the aperture by a bridge of material and which includes two branches extending, on either side of the bridge of material, generally towards the arbour. Each branch includes a support surface in proximity to the free end thereof. The invention also proposes a timepiece fitted with an assembly element of this type.
