Abstract
A metal heat exchanger tank has a molded plastic attachment bracket that can be secured thereto anywhere along the length of the tank with a simple press fit that is very solid. A relatively short metal flange running the length of the tank is inserted into a pocket on the plastic bracket, as cross beams in the pocket insert within notches in the flange and resilient fingers in the pocket snap into indentations in the flange. The bracket is thus preventing from pulling away from the tank or from shifting along the length of the tank. One pocket wall is long enough to cover most a flat back of the tank, which is flush to a back face of the flange, and a footer on the bracket abuts with a flat side of the tank. This gives great twisting resistance to the bracket in any direction relative to the tank.
