A system and method are disclosed to attach a blade section (2) of a fan blade (1), in particular of a smoke extractor fan, to a fan hub, as well as a fan blade (1), which provides a high tensile strength even at high temperatures. The attaching part and fan blades (1) are to be produced so as to save as much weight as possible. The attaching part has a connecting section (5) embodied to produce a high-tensile connection to a blade section (2) of a fan blade (1). The connecting section can be arranged essentially in the interior of the blade section (2).
