A link device for safety linking of a first member to a second member includes a first element, a second element, and a fluidic vibration transfer mechanism. The first element includes a first link end adapted to be directly linked to the first member, and a second link end adapted to be directly linked to the second member. The second element has a first link end adapted to be directly linked to the first member, and a second link end adapted to be directly linked to the second member. The fluidic vibration transfer mechanism links the first and second elements of the link device to one another, and includes at least two pressure chambers filled with a pressurized liquid, separated by at least one piston integral with the first or second element.

A structural rod has a primary rod that has an axial cavity and a secondary rod inside the axial cavity so that the secondary rod is able to move inside the axial cavity along the direction of the longitudinal axis of the rod. The primary rod has a bearing for fastening the structural rod at the first end in a rigid manner and is not fastened rigidly to the structure at the second end. Conversely, the secondary rod has a bearing for fastening the structural rod at the second end in a rigid manner and is not fastened rigidly to the structure at the first end. The primary and secondary rods are joined through one or more intermediate linkage elements made of a deformable and elastic material.

An assembly for connecting a first body to a second body includes a first element having a connection end to the first body and a first tubular portion, and a second element having a connection end to the second body and a second tubular portion extending along the longitudinal axis. The first tubular portion and the second tubular portion are interlocked by at least one complementary tubular portion nested in the first tubular portion and around the second tubular portion. A rigid piece connects the first body to the second body and is fastened to the first and second bodies. One of the first and second bodies is connected with functional play at one of the two attachment points of the rigid connecting piece, wherein the rigid connecting piece is formed of two flat rigid pieces extending on both sides of the first and second elements along the longitudinal axis.
