The assembly pin comprises a tubular piece (1) which has at one of its ends (11) two slots (12,13) placed diametrically opposite. The other end is surrounded by a sliding sleeve (4) in the form of a cylinder with a collar (41) to facilitate its movement. The sleeve is prevented from sliding too far by a blocking ring (6) and is joined to a spring (5) which ends in two clamping hooks (500,520) which project through the corresponding slots at the end of the tubular piece. These hooks retract into these slots when the sleeve is slid from its blocking position, by the blocking ring, towards the end of the tubular piece opposed to that containing the slots.
