A device is disclosed relating to sheet metal duct connections, particularly where sections of metal ducts must be joined during construction of metal duct work. A connecting device cuttable to any desired length without substantial waste can be inserted on a segment of duct and joined to a wall or second duct surface having an opening cut to the size of the first duct to which is attached the connecting device. By manual manipulation, the connecting device can then anchor the first duct to the wall or second duct opening.

A connecting device for anchoring a duct segment to an opening in a wall, the duct segment having a peripheral edge portion closely receivable into the opening, the connecting device being formable of integral construction from a metal sheet of substantially uniform thickness and comprising a plurality of strips defined by bending said sheet along crease lines, the strips including first and second gripping strips and first and second flange strips, said first and second gripping strips being adapted for grippingly fitting over said peripheral edge portion of the duct, said first and second gripping strips being connected to said first and second flange strips along a joint and being substantially orthogonally aligned to said second flange strip and in parallel alignment with said first flange strip, said first and second flange strips being positioned to abut against said wall in close proximity to the opening, said first flange strip including a plurality of tabs substantially orthogonally aligned to said second flange strip and being manually bendable around said opening to a position parallel to said second flange strip with the portion of the wall immediately adjacent said opening included therebetween, whereby secure anchoring of the duct to the wall around said opening is effected.
