A mounting member for a filament assembly comprises a generally planar base portion and a pair of projections integral with the base portion, the projections having cut-outs therein in which are received respectively a pair of mounting lugs on a base of the filament assembly. The projections are deformed from positions in which they are generally co-planar with the base portion and extend into an aperture formed therein, and positions in which they upstand from the base portion and are of helical configuration. In their undeformed positions, the projections overlap one another and are spaced apart transversely of their direction of extent. Thus, the length of the projections is not limited by the size of the aperture, which must accommodate the external cross-section of the filament assembly base therein. |
