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.

Abstract: A connection device for assembling together 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 being intended to be received in stationary manner in the inner cavity of the receiver member and including a cage forming a pair of jaws for coming into engagement in the groove of the fastener member through its constricted opening, the device including a spacer member for spacing the jaws apart, and actuator means for moving the spacer member relative to the jaws, the actuator means including a pivotable lever that pivots about a first pivot pin, wherein the actuator means also include a connection bar that is connected to the lever via a second pivot pin and to an abutment element via a third pivot pin, the three pivot pins being parallel, the distance between the first pin and the third pin being variable by actuating the lever.
