ABSTRACT A pair of frame members are secured to the ends of pair of adjacent generally circular ducts. Each frame member has a generally circular configuration and has an inner vertical wall, an outer vertical wall. The outer vertical wall is connected to a sloped rigidifying portion which extends outwardly from the inner vertical wall. Both the inner and outer vertical walls have horizontally extending flanges which are in abutting relation and their end portions are clampingly engaged. The frame members have a circumferential dimension less than the circum- ferential dimension of the duct member so that a gap is formed in the circular frame member. The frame members are positioned on the duct end portions by inserting the frame member flange portions inside the duct end portions with the top surface of the frame member upper flange abutting the underside of the duct. Fasteners secure the duct end portion to the flange members and are applied to the flange member and duct end portion to urge the frame member flange portion against the undersurface of the circular duct.
