Process and device for connecting a submersible element to an enclosure under very high pressure ABSTRACT The invention relates to a device for connecting a cylindrical or tubular submersible element to a tubular sleeve, inter alia a submersible heating element to the sleeve of a pressurizer basin, comprising a first flange associated with the sleeve, a second flange associated with the submersible element, a resilient metal joint interposed between the two flanges, two screwthreaded tubular members, one male, the other female, which cooperate with one another via their threads, the threaded male member acting on the first flange via the agency of two half-rings, the female screwthreaded member acting on the second flange, the screwing of the two screwthreaded tubular members causing the compression of the joint. It is characterised in that the joint comprises a T section, the flanges each having an end bearing surface and a frustoconical bearing surface cooperating respectively with the main member and crossbar of the T, the second flange comprising a thrust shoulder at one end of the connecting device, and the male screwthreaded element comprising a thrust edge at the other end of the joint, so that the joint can be precompressed by tightening the two elements and bringing them together.
