<p>The file (2) has a sheet (4) forming a side (44) extending on a side of a bottom. Two suspension bars (6) are respectively equipped with hooks (64, 66) at ends. The hooks have rectilinear internal edges (642, 662) and rectilinear external edges (644, 664) inclined with respect to a longitudinal axis (X6) of the bars at angles (alpha1, beta1) ranging between 60 and 80 degree Celsius. One of the external edges of one of the hooks remote from an edge (446) of the sheet is parallel to each internal edge while the external edge is remote from a bottom (666) of the hook.</p> |
