The device has wedges (32, 33) made of vibration damping material and interposed between a protector (1) and a structure (2) at a level of a fixing unit (31) and between the protector and a head of the unit, respectively. A filtration wedge is in-between an outer edge (12) of the protector and a lateral side (221) of the structure. The wedges (32, 33) have holes (34) traversed by a rod (312) engaged in an orifice (13) of the protector. |
