A pipe coupler connection apparatus for duct is provided to increase the heat exchange efficiency by blocking the dampness leakage. A pipe coupler connection apparatus for duct comprises a duct(10), a pipe coupler(11) and resilient fastener(20). The duct adapts ribs(30) and holding unit(31) in a joint groove(33). A ±Ý-shaped fixture(23) is formed in both sides of the pipe coupler. The resilient fastener has holding pieces(21) on the leading end. The fixture is assembled in a square hole(22) which is formed in the center of resilient fastener.
