Body (1) of connecting rod has two external grooves (8, 9) extending along longitudinal axis X between two sleeves (2, 3), a third groove (10) extending perpendicular to axis X. Third groove has two ends (11 a, b) connecting to external grooves so as to define two symmetrical halves (10 a, b) relative to plan P. External grooves have two sections (8 c, e; 9 c, e) diverging from sleeves and defining angle larger than 10 degree with longitudinal axis X. |
