A spring 1 is installed inside the fixing element 5, which is supported by a plug 5 made with a base on which there are threads and holes. An axis is attached to the base, on which spring 1 is installed.

The holes made in the base of the plug 5 are necessary for screwing and unscrewing the plug from the cylinder of the glass 2.

A hole is made in the cover with a diameter corresponding to the outer diameter of the cylinder of the glass 2. The cylinder of the glass 2 is tightly (due to the elastic properties of the material of the cover) inserted into the hole of the cover, so that the flange of the cylinder is adjacent to the inner part of the cover, and the cylinder of the glass 2 protrudes over the outer parts of the cover. The reinforcement of the decorative part 4 is installed on the protruding part of the cylinder, so that part of the spherical clamps 7 fits into the annular groove of the reinforcement of the decorative part 4. A fixing element 3 with a spring 1 and a plug 5 is inserted inside the cylinder of the glass 2. In this case, the conical stops of the fixing element press on the remaining part of the spherical clamps protruding from the holes, thereby fixing the reinforcement of the decorative part. An NFC chip 8 is installed between the fittings of the decorative part 4 and the decorative part of the accessory 6.

The case with the installed accessory is installed on the mobile device.

If it is necessary to replace an accessory, remove the mobile device from the case, and then:

- press on the fixing element 5, which is lowered into the inside of the cylinder of the glass 2, while the spherical clamps come out of the annular groove of the fittings of the decorative part 4 and remove the decorative part of the accessory 6 with the fittings of the decorative part 4, install a new decorative part of the accessory 6 with the fittings of the decorative part 4 and release the fixing element 5. Next, the case with the new decorative part of the accessory 6 is installed on the mobile device.

Thus, the claimed invention proposes a simple, reliable and safe mechanism for attaching an accessory with replaceable decorative parts to the case of a mobile device. The fixing element is securely installed in the accessory for the mobile device case, due to the spring, which prevents the fixing element from falling spontaneously and holds it in the upper position, while the conical stops press on the spherical clips, and they, protruding from their holes, fix the fittings of the decorative part .
