Abstract
In an arrangement for connecting tube elements of a ventilation duct system, the inner tube (3) has an abutment (7') for engagement with a matching abutment (8') of the outer tube (1). By insertion of the inner tube (3) into the outer tube (1), the abutments (7', 8') are brought into engagement in a plane (P) perpendicular to the direction of insertion for providing coupling between the abutments and thereby connection of the tubes (1, 3). The abutment (7') of the inner tube (3) is continuous along the circumference of the tube (3) and is provided at a distance (d) from a free end (20) of the inner tube (3).
