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).
Dans un agencement destiné à raccorder des éléments de tube d'un système de conduit de ventilation, le tube interne (3) possède une butée (7') destinée à être couplée à une butée correspondante (8') du tube externe (1). Lors de l'insertion du tube interne (3) dans le tube externe (1), les butées (7', 8') sont couplées dans un plan (P) perpendiculaire à la direction d'insertion afin de permettre le couplage entre les butées et de relier ainsi les tubes (1, 3). La butée (7') du tube interne (3) est continue le long de la circonférence du tube (3) et se trouve à une distance (d) de l'extrémité libre (20) du tube interne (3).
