Abstract
An anode rod is placed between two hooks fixed to an anode beam and onto which a connector bears, including two levers, two coaxial lateral rods and a screw that can pivot levers between a clamping position of the anode rod in contact with the anode beam and a release position. The geometry of at least one hook, a lever and/or a lateral rod and the material from which they are formed are such that the elastic deformation of the holding device with respect to the anode beam when the screw is tightened is sufficient. Thus, this device can compensate for a change in the position of the anode rod by elastic return towards its unstressed position, and thus continues to keep the anode rod firmly in contact with the anode beam.
