Abstract

The lower cover plate of an electric hotplate is fixed to the hotplate body by a resilient fixing structure provided on the cover plate, engaging with gripping edges on the outer face of a downwardly directed, central cast pin. The fixing structure can be defined by radial or flap-like, inwardly-directed portions of the cover plate and additionally can have portions engaging on the lower face of the pin and which are firmly held by the final screwing down of the electric hotplate.
