Patent ID: 7727362

Claim:
A sacrificial anode for cathodic corrosion protection, comprising an anode body ( 1 ), a mounting component ( 8 ) for mounting the sacrificial anode on the device to be protected, an insulating component ( 4 ) that in certain areas surrounds the anode body ( 1 ) and electrically insulates the anode body ( 1 ) from the mounting component ( 8 ), and a resistive element ( 9 ) that is inserted between the anode body ( 1 ) and the mounting component ( 8 ), wherein the insulating component ( 4 ) is fixed on the mounting component ( 8 ), characterized by the fact that a securing component ( 6 ) is fixed on the anode body ( 1 ) and prevents the anode body ( 1 ) from moving out of the insulating component ( 4 ), wherein said securing component includes an outside diameter and said insulating component defines an inside diameter, said outside diameter being larger than said inside diameter.
