A duct joining system having two L-shaped connectors for each duct corner. Each connector has two substantially perpendicular legs forming a corner region and has an inside and an outside surface with the outside surface of one L-shaped connector abutting the outside surface of the other L-shaped connector when the ducts are joined. A orifice is formed in the corner region of each L-shaped connector in alignment with the orifice in the abutting connector. A cleat is integrally formed with and extends inwardly from the peripheral edge of each of the orifices. A score line is formed at the base of each cleat on the outside surface of the connector to allow the cleat to be bent outwardly about the score line so as to extend through, and over the peripheral edge of, the orifice in the abutting L-shaped connector to lock the connectors together.
