Claim:
A protective case for transporting or storing a plate-shaped part pierced with an aperture, the protective case comprising: (a) a back cover; (b) a cover, wherein the back cover and the cover each have a rim and the rims fit into each other when the case is closed; (c) a mobile flange inserted in the back cover and held laterally by the rim thereof; (d) clamping means for immobilizing the plate-shaped part, wherein the clamping means include (i) an elastically deformable stake that is mounted on the top surface of the mobile flange and is inserted in the aperture of the plate-shaped part; (ii) a projecting portion formed under a bottom surface of the cover, wherein the projecting portion is arranged to press against the stake when the case is closed so as to increase an external diameter of the stake to jam the stake in the aperture of the plate-shaped part; and (e) elastic means provided under the mobile flange to return the mobile flange and the stake that the mobile flange carries in the direction of the cover with sufficient force to hold the stake jammed in the aperture of the plate-shaped part.
