<p>The casing has an annular flange (118) including passage orifices of a screw (126) that fixes the casing to a structural element i.e. flange (116) of turbomachine. The screw extends across the orifice and tubular spacers (138, 140) are connected on a side of the flange. The spacer (138) is axially locked on the flange (118) by a nut (136) screwed on a threaded part of the screw and includes a cylindrical clamping skirt (144) on a side of the flange. The skirt is engaged and crimped in the orifice to maintain the spacer (138) on the flange during the loosening of nut and disassembling of screw.</p> |
