Flexible connection arrangement for the two pipe portions particularly for motor vehicle exhausts

In a flexible connection arrangement for two pipe portions, particularly in motor vehicle exhaust systems, having a metallic bellows which is connected axially on either side in a gastight manner with connection pieces in the form of substantially cylindrical sleeves, wherein the sides of the connection pieces facing the bellows have radially widened end portions with substantially cylindrical end portions, also having a damping insert which extends coaxially relative to the bellows along its length and is in a working connection therewith, and heat protection means for the bellows acting in the radially inward direction, the improvement comprising:

• said damping insert enclosing the bellows radially outwardly such that turns of the bellows contact said damping insert, axial end regions of said damping insert being supported radially outwardly by cylindrical end regions of said widened end portions of said connection pieces and being held in said widened end portions without being fastened thereto by said bellows and said widened end portions;
• said connection pieces being connected with one another via a spring which surrounds the damping insert radially outwardly and applies compressive force thereto;
• and
• said heat protection means being formed by a pipe segment which extends within the bellows coaxially relative to the bellows at a radial distance from said bellows and which is fastened to the connection piece located in the front as viewed in the direction of flow.
