The invention concerns a device for securing at least one part onto the bottom of a case including at least one stud which projects from said bottom, said part having at least one substantially flat portion provided with an orifice having an axis substantially perpendicular to said bottom and into which said stud is introduced. The case further includes a cover provided, on the face thereof which is directed towards the bottom of said case, complementary means to said stud for, in a closed position of the cover, applying and holding said flat portion onto a support surface provided in the region of said bottom, and means for blocking the cover onto said case. Said complementary means are shaped for generating deformation of said distal portion outwards so that said deformed distal portion of said stud is inserted between said flat portion and said complementary means.
