Abstract
A sealed joint between a basin (21) and a plate (43) as in the construction of a heat exchanger tank. The basin has a rim with an outwardly directed flange (23), and the plate has a rim including a U-shaped channel (42) to receive the flange together with a gasket (65). The gasket comprises at least a fillet which is suitable for being elastically deformed by being compressed between the flange and the channel to fill the space therebetween. The portion (100) of the fillet which faces the flanges is narrower than the portion (100') of the fillet which faces the channel by virtue of at least one setback (104) in the fillet between said portions thereof.
