Abstract

A duct connector is provided to facilitate connection between the double duct and the straight double duct or connection between the straight duct and the fitting duct. A duct connector(A1) is formed by injection-molding flexible plastics to have a receiving space(2) and includes an outer wall(4) of H-shaped cross section, where fitting grooves(41,42) are formed symmetrically on both sides. The fitting grooves have first and second slopes(43,44) on the insertion side end. One of the first and second slopes are inclined outward to be adapted to the air current.
