Releasable coupling for a suspension stud on a wall of a mobile telephone

Releasable coupling for a suspension stud on a first face of a wall, especially of a casing of a mobile item of telecommunication, of the type comprising:

• an orifice made in the wall and emerging on said first face of the wall;
• and
• a device for axial retention of the stud, a coupling end of which is accommodated in said orifice in order to perform the coupling,
• characterized in that said orifice emerges on the second face of the wall opposite said first face and said retention device includes a rod which passes through the orifice and is provided at its free end with means for bearing axially around the perimeter of the orifice on the second face of the wall, which retention device can move, along a coupling path, between a coupling position in which the axial bearing means are applied against the second face of the wall, the wall lying between the stud and the axial bearing means, and an uncoupled position in which the axial bearing means are disengaged from said wall, and in that means are provided for immobilizing the retention device with respect to the wall in its coupling position.
