Abstract: A connection device for assembling together a receiver first section member presenting an inner cavity, and a fastener second section member presenting a groove having a constricted opening. The connection device includes a cage forming a pair of jaws for coming into engagement in the groove. The device also including a resilient drive mechanism for urging a spacer member between the jaws so as to space them apart in such a manner as to come into engagement with the groove through the constricted opening; and a pivotable lever that pivots about a pivot pin, the pivotable lever including a lever arm and a thrust head that engages the spacer member so as to move it against the force exerted by the resilient drive mechanism on the spacer member.

Abstract: A connection device for assembling a receiver first section member presenting an inner cavity and a fastener second section member presenting at least one groove having a constricted opening, the connection device to be received in the inner cavity of the receiver member and including a cage forming a pair of jaws for engaging the groove of the fastener member through its constricted opening. The device includes a spacer member for spacing the jaws apart, and an actuator mechanism for moving the spacer member relative to the jaws, the actuator mechanism including a pivotable lever that pivots about a first pivot pin. Then actuator mechanism includes a connection bar connected to the lever via a second pivot pin and to an abutment element via a third pivot pin, the three pivot pins are parallel, the distance between the first pin and the third pin being variable by actuating the lever.
