ABSTRACT:
The invention relates to multiple unions of the type comprising two plates which carry elementary unions and which are brought close together or spaced apart, by force, with the aid of at least one maneuvering device of the rack and pinion type. Initial latching of the two plates is ensured by a bolt-pillar mechanism, the pinions having on the shaft an angular clearance enabling them to remain immobile and to allow unlocking when the handle begins its movement for the separation of the two plates. With this handle are associated locking means which ensure retention thereof in locked position.
