An aircraft fuselage including at least two sections kept assembled at a circumferential join, each section having at least one panel. The circumferential join includes at least one inner ring, situated on one face, called the inner face, of the fuselage. The inner ring has a width li, partially overlaps each of the two panels and is fixed to the two panels by fasteners. The fuselage also includes an outer ring, situated on one face, called the outer face, of the fuselage, opposite to the inner face. The outer ring has a width le, partially overlaps the two panels, and is fixed to the two panels and to the inner ring by some or all of the fasteners fixing the inner ring to the two panels.

The invention claimed is: 1. Aircraft fuselage, comprising at least two sections kept assembled at a circumferential join, each section comprising at least one panel, substantially with a thickness ep, said circumferential join comprising at least one inner ring situated on one face, called the inner face, of the fuselage, said inner ring having a width li and partially overlapping each of said two panels, said inner ring being fixed to said two panels by fasteners, characterized in that the fuselage comprises an outer ring situated on one face, called the outer face, of the fuselage, opposite the inner face, said outer ring having a width le smaller than the width li of the inner ring, and partially overlapping the two panels, said outer ring being fixed to said two panels and to the inner ring by only a portion of the fasteners fastening the inner ring to said two panels. 2. Aircraft fuselage according to claim 1 wherein the outer ring is thinner than the inner ring. 3. Aircraft fuselage according to claim 1 wherein each panel comprises, substantially symmetrically on either side of the circumferential join, a face offset in depth relative to the outer face in the thickness ep of the panel, the outer ring being positioned wholly or partly on the two offset faces. 4. Aircraft fuselage according to claim 3, in which the material forming the two panels is made of composite material and in that the offset faces are made by means of a dimpling of said two panels. 5. Aircraft fuselage according to claim 3, in which the material forming the two panels is made of a composite material and in that the offset faces are made by means of a rebate of said two panels. 6. Aircraft fuselage according to claim 1, in which the material forming the outer ring is different from that forming the inner ring. 7. Aircraft fuselage according to claim 1, in which the material forming the outer ring is made of composite material.
