<p>The invention concerns a single piece mounting box (100), produced from a blank shaped in a press and comprising a substantially planar sole plate (102) with an aperture defined by a closed outline for the passage of an arm and at least two fixing holes (134), a U-shaped support wall (106) perpendicular to the sole plate (102) plane and comprising a base (108) and two mutually parallel branches (110) located on either side of said aperture, said support wall (106) being formed by folding a blank portion initially spaced from said aperture, and retaining means between said sole plate (102) and said support wall (106) preventing, by the restoring force of a spring (50), the support wall (106) branches (110) from being spaced from said sole plate (102).</p> |
