Abstract:
1. A combination of a partitioning and a ductwork for leading at least one pipe through an opening in said partitioning, wherein said ductwork includes a flange with an outer periphery area and a central area which is provided with a guide opening for each of said at least one pipe, the flange being provided with a number of mounting apertures arranged in the outer periphery area, wherein the mounting apertures are formed in the central area, the flange having an inner side and an outer side opposite the inner side, where the inner side is adapted for bearing against one side of the partitioning, wherein the ductwork further includes a connecting arrangement mounted in each mounting aperture, the connecting arrangement including; a force transmission means with an operating member disposed over the outer side of the flange, and with a shank extending through the mounting aperture, a clamping means disposed on the shank of the force transmission means and which is displaceable around and/or along the shank by actuating the operating member, wherein the shank and the clamping means are provided with an interacting screw thread, and an engagement arrangement disposed between the inner side of the flange and the clamping means, wherein the engagement arrangement includes a pivot arm provided with engagement faces and contact faces, wherein the engagement faces may be displaced radially relative to the orientation of the shank, wherein the contact faces of the engagement arrangement are interacting with contact faces of the clamping means to provide fixed or frictional connection for transmitting torque from the clamping means to the pivot arm, and that the pivot arm is displaceable by rotation about the shank from a free position with the engagement faces within the periphery of the central area and with an engagement position with the engagement faces outside the periphery of the central area such that the engagement faces come into contact with the other side of the partitioning, wherein the contact faces of the clamping means and/or the contact faces of the engagement arrangement are inclining.
