Assembly element ( 18 ) made in a plate of brittle material, including an aperture ( 32 ) provided for the axial insertion of an arbour ( 26 ), the inner wall ( 33 ) of the aperture ( 32 ) including elastic structures ( 34 ), which are etched into the plate to grip the arbour ( 26 ) radially. Each elastic structure ( 34 ) includes a first rectilinear elastic strip (L<SUB>1</SUB>) which extends along a tangential direction relative to the arbour ( 26 ). According to the invention, each elastic structure ( 34 ) is formed by a radial stack of several parallel elastic strips. The invention also proposes a timepiece fitted with this assembly element ( 18 ).
