A tube bundle heat exchanger including elastic sealing means wherein the elastic medium is confined within separate chambers and compressed in all directions against the inner wall surface of the chambers and heat exchanger tubes within the chamber. Pressure plates that exert pressure on the elastic medium are provided with projections which provide a spacing between the pressure plates. This spacing may be used for inspection for leaks and also permits flow of fluid to the outside if there is a leak.
