A polygonal tube rack connector includes a lid and a carrier incorporated to each other by means of multiple fasteners; multiple non-linear grooves are disposed on the connector to accommodate mounting of multiple linear tubes; a limiting hole being disposed to each groove to facilitate fast and direct insertion of a stud from a tube to secure the tube in the groove without slipping off; and the tube can be easily removed by loosening up those fasteners for replacement.
