摘要： The invention relates to an attachment for attaching structural elements having aligned bores having a nominal diameter (D), the attachment including a minimum tightening plane (Gmin) and a maximum tightening plane (Gmax), and a screw (12) including a widened head and a threaded portion (22), a sleeve (30) including a widened head, a cylindrical tubular body and a tapped portion (36) interlocking with the threaded portion (22) of the screw, the tapped portion (36) being adjacent to an inwardly smooth portion of the body (34) of the sleeve, said smooth portion having a thickness (E), a not easily deformable area (A) adjacent to the head of the sleeve and a deformable area (B) adjacent to the not easily deformable area (A), the deformable area (B) of the sleeve can deform to a bulb (48) intended to come into contact with a blind surface (46) of the structural elements. The deformable area (B) extends along a length (L) greater than a minimum length (Lmin) and less than a maximum length (Lmax), such that: Lmin = D/2 + 2E + (Gmax - Gmin), Lmax = (E/0.092). The invention applies in particular to the assembly of aircraft structures.
