  • the fastening ring has at least one protruding locking projection and / or a recessed locking recess on the ring body. These act together with the recessed locking recesses or protruding locking projections on the short tubular ring section and thus form a locking connection between the fastening ring and the tube section.
  • This latching connection by means of a fastening ring holds the hotplate on the hob plate of the hob when the fastening ring is additionally supported on the hob plate or its underside.

  • Said locking projections on the circumferential ring body of the fastening ring can advantageously be provided as separate parts and attached to them.
  • Ring bodies and locking projections are particularly advantageously made of metal and are connected to one another by welding. Even if a latching recess is provided on the ring section of the hotplate body all the way round or continuously, it is advisable not to design the latching projections continuously so that, although they are preferably equally distributed, they are provided for a uniform and secure latching connection.
