PROBLEM TO BE SOLVED: To provide a connection device for a flexible air duct capable of not only effectively preventing an air leakage with a simple structure but also facilitating the connection and separation work at a low manufacturing cost. SOLUTION: The connection device for the flexible air duct provides slide fasteners F on the connection end sections 1a and 2a of two unit flexible air ducts 1 and 2 to be connected to each other, skirts S1 and S2 are respectively and integrally mounted to the inside surfaces in the vicinity of the connection end sections 1a and 2a, and the connection device of the flexible air duct is so constituted that either one skirt of two skirts S1 and S2 can cover the slide fasteners F from the inside by the direction of the wind to prevent the air leakage.
