In this flange, each oblong hole (2) is made, on the one hand, so that the direction of its longitudinal axis (A) is neither parallel nor perpendicular to the line (B) passing through the axis (O) of the flange and through the centre (C) of the hole (2) and, on the other hand, so that its width (l) is such that it satisfies the equation l >/= D + DELTA cos alpha where D is the diameter of the pins which join the flange to the other flange, DELTA is the magnitude of the tolerance for positioning the assembly pins on the other flange (or the holes for the passage of these pins) and alpha is the angle formed between the longitudinal axis (A) of the hole (2) and the aforementioned line (B). <IMAGE>
