Connecting assembly for connecting two structures (130, 150) of an aircraft, the connecting assembly comprising: - a central element having a through-hole, preferably a bore, designed to make a connection with one of said two structures by virtue of a fastener element (160, 161) comprising a shank inserted into the through-hole, - a plurality of deformable shock-absorbing elements (106, 108), referred to as first shock-absorbing elements, each of the first shock-absorbing elements (106, 108) being, on the one hand, secured to said central element and, on the other hand, configured to bear against a surface of the other structure of the two structures (130, 150), - at least two other shock-absorbing elements (107, 109), referred to as second shock-absorbing elements, manufactured from a deformable material, and, on the one hand, secured to the central element and, on the other hand, extending as far as a predetermined distance away from a surface of the other structure, the second shock-absorbing elements (107, 109) potentially comprising one or more metal inserts or inserts made from a material other than said deformable material, and/or one or more cavities arranged in the deformable material, the connecting assembly being characterized in that: - said first shock-absorbing elements (106, 108) each extend outwards, from the central element, in a direction perpendicular to a longitudinal axis of said through-hole, and in that: - said second shock-absorbing elements (107, 109) each extend outwards, from the central element, in a direction perpendicular to the longitudinal axis of said through-hole, which direction is different from the direction in which the first shock-absorbing elements (106, 108) extend. - a central element having a through-hole, preferably a bore, designed to make a connection with one of said two structures by virtue of a fastener element (160, 161) comprising a shank inserted into the through-hole, - a plurality of deformable shock-absorbing elements (106, 108), referred to as first shock-absorbing elements, each of the first shock-absorbing elements (106, 108) being, on the one hand, secured to said central element and, on the other hand, configured to bear against a surface of the other structure of the two structures (130, 150), - at least two other shock-absorbing elements (107, 109), referred to as second shock-absorbing elements, manufactured from a deformable material, and, on the one hand, secured to the central element and, on the other hand, extending as far as a predetermined distance away from a surface of the other structure, the second shock-absorbing elements (107, 109) potentially comprising one or more metal inserts or inserts made from a material other than said deformable material, and/or one or more cavities arranged in the deformable material, - said first shock-absorbing elements (106, 108) each extend outwards, from the central element, in a direction perpendicular to a longitudinal axis of said through-hole, and in that: - said second shock-absorbing elements (107, 109) each extend outwards, from the central element, in a direction perpendicular to the longitudinal axis of said through-hole, which direction is different from the direction in which the first shock-absorbing elements (106, 108) extend.
