A fixing device for detachably fixing a heating element to a sleeve welded to the body of the pressurizer of a nuclear reactor comprises an assembly of members with a symmetry of revolution, the axes of the members being coaxial with the heating element. The members comprise a gasket-carrying collar made integral with the heating rod and which bears on the outer face of a shoulder on the sleeve, a two-part ring which bears on the inner face of the shoulder on the sleeve, a screw-threaded nut and a screw-threaded tubular collar which are threaded together and bear respectively on the collar and the ring. The nut is provided with an opening for water leaking from the pressurizer and a zone of reduced thickness along which the nut can be cut in the event of seizure of the nut and tubular collar.
