ABSTRACT:
A duct fitting of generally cylindrical configuration for attachment to a relatively large, generally cylindrically-shaped flexible duct having a curved sidewall of easily deformed material, in which sidewall a hole of particular size has been created. This duct fitting is constructed of deformable sheet material and has first and second open ends, with the first end having a curvature conforming to the configuration of the curved sidewall of the flexible duct. The second end of the duct fitting is adapted to receive thereon, a relatively small branch duct to be connected in a leak-free manner to the flexible duct. In accordance with this invention, the first end of the duct fitting has a plurality of short, lateral slots disposed at spaced locations around its circumference, thus to define a plurality of bendable teeth arranged in a non-planar array. These teeth are insertable into the hole created in the curved sidewall of the flexible duct, and then bent over into conforming engagement with the curved interior surface of the flexible duct, thus to lock the duct fitting into the flexible duct. I may use a flat ring of curved contour on the exterior of the duct fitting for limiting the insertion of the first end of the duct fitting into the flexible duct, and I may use a second flat ring on the interior of the flexible duct, for preventing any tearing by the teeth of the interior of the flexible duct.
