<p>An improved joint flange for connecting air duct sections by means of a "snapp in" type operated connection comprises a first hollow vertical leg and integral therewith a horizontal leg terminating in an open-ended slot or jaw for frictionally engaging a duct end portion (20). The base wall of the first leg cooperates in the duct end connection. The lower side of the L-profile is provided with an integrated means (31) for the fixation or support of an air channel insulation, said means being formed by a sheet material ply located below the duct end engaging base wall (30) of said first leg. A material-saving, cost-effective and flexible joint member is achieved by an inventive L-profile of less complication.</p> |
