Abstract: The present invention relates to a connection assembly (1) for reversibly connecting in a sealing manner a first female tubular element (10) made of a first metallic material to a second male tubular element (12) made of a second metallic material different from the first material, comprising: a) at least one flange (10b) radially extending from the first (10) and/or from the second (12) tubular element; b) a coupling element (30) made of plastic of the tubular elements (10, 12) comprising a fork-shaped body (30a) configured to axially cooperate with the end portions of the tubular elements (10, 12) at the flange (10b) so as to prevent a reciprocal axial sliding of the tubular elements (10, 12); c) a bushing (20) made of plastic reversibly coupled in a sliding manner within the end portion of the first female tubular element (10) and comprising a substantially cylindrical body (21) associated to a radially inner wall of the end portion of the first female tubular element (10) and configured so as to receive in a sliding manner and with substantial shape coupling a free end portion of the second male tubular element (12); d) at least a first radial sealing element (22, 24) associated to a radially outer wall (21a) of the substantially cylindrical body (21) of the bushing (20) and configured so as to cooperate in a sealing manner with a radially inner wall (10a) of the end portion of the first female tubular element (10); and e) at least a second radial sealing element (14) arranged between an end portion of the second male tubular element (12) and a radially inner wall (21b) of the substantially cylindrical body (21) of the bushing (20). The present invention also relates to the bushing (20) included in such a connection assembly (1) and to a heat exchanger (5) provided with a tubular joining element (10) including such a bushing (20).
