Abstract: The invention relates to an arrangement for sealing an end section of a tube or of a tubular vessel with a sealing plate arranged pointing toward the tube, and a front plate arranged pointing away from the tube. A peripheral seal is arranged in the outer region of the plates and is disposed at least partly between the sides which point toward one another. The invention provides an arrangement for sealing an end section of a tube or of a tubular vessel, which prevents passage of a medium either out of or into the vessel. This is achieved by virtue of the arrangement, where on at least one of the sides of the plates pointing toward one another in the sealing region, there is a projection which, when forced by pressure onto the sealing plate, brings about a deformation of the seal in the direction of the inner wall of the tube or tubular vessel.
