摘要

Fixing device of a blade (20) to a profiled support (23) comprising a rod (2) provided at one of its ends with a head (5) adapted to be inserted in a groove (22) of the blade (20), and to the other end, two arms (11) adapted to occupy, in the support section (23), a first position in which said arms (11) are substantially parallel to the longitudinal edges of the profiled support (23), and a second fixing position, in which said arms (11) are engaged under the wings (24) of the profiled support (23). The rod (2) is threaded and the said head (5) has an upper face provided with a housing for receiving a tool for driving in rotation of the device and a lower face with, symmetrically with respect to a diametral zone thick, two zones of reduced thickness toward the periphery, each zone of narrowing forming at least one inclined ramp adapted to cooperate with said groove (22) of the blade (20) during the rotation of the device of the demounting position to the position of fastening.
