The invention provides a locking pin (G) comprising a loop (B) and means (R) for pivoting the loop on the locking pin so that said loop (B) may be brought back to surround the spindle (A) in which the locking pin is engaged so as to oppose removal of said locking pin. The pivoting means (R) comprise a mobile bearing (6) supported by two substantially parallel arms (8, 9), the assembly being such that in a "high" position the arms extend on a side which moves the bearing (6) to a maximum away from the opposite end (e) of the locking pin, whereas in a "low" position, said arms (8, 9) have rotated with respect to the "high" position. The locking pin may pass through the loop when the arms are in the "low" position but cannot pass through the loop when the arms are in the "high" position.
