The shank (1) presents two transverse sections forming a T-shaped profi le according to the sections BB and CC, and the T-shaped profile defines a unique height (G2) along an extent (S5) of the shank (1), and a unique width (S4) on a line (C1) extendi ng along an area of a section (T1) of the extent (S5) that is equal to a width (S4) on a line (C2) of another section of the extent (S5).
