Coupling device for a connecting rod

An aircraft comprising:

• an aircraft fuselage with a fuselage structure formed therein;
• and
• a coupling device attached to the fuselage structure, the coupling device comprising:
• a first coupling element, and
• a second coupling element, which can be coupled to the first coupling element,
• wherein the first coupling element has an elongate body, which has a first channel structure on a lateral surface along a first longitudinal axis,
• wherein the second coupling element has a hollow-cylindrical portion having a first axial length, which, on an inner face along a second longitudinal axis, has a second channel structure complementing the first channel structure, the first axial length extending from a first end of the hollow-cylindrical portion to a second end of the hollow-cylindrical portion along the second longitudinal axis,
• wherein the hollow-cylindrical portion has a radial cutout through which the elongate body can be inserted into the second channel structure from outside the hollow-cylindrical portion in a radial direction,
• wherein the second coupling element has a closure body, which is configured to close the radial cutout, can be positioned removably in the cutout and completes the second channel structure on a radially internal face, the closure body having a second axial length, the second axial length extending from a first end of the closure body to a second end of the closure body along the second longitudinal axis,
• wherein the second coupling element also has a securing element, which can be pushed onto the hollow-cylindrical portion to secure the closure body on the hollow-cylindrical portion, and
• wherein the first axial length is greater than the second axial length.

A coupling device for a connecting rod for at least one of attaching a component to a fuselage structure of an aircraft or stiffening the fuselage structure, the coupling device comprising:

• a first coupling element, and
• a second coupling element, which can be coupled to the first coupling element,
• wherein the first coupling element has an elongate body, which has a first channel structure on a lateral surface along a first longitudinal axis,
• wherein the second coupling element has a hollow-cylindrical portion, which, on an inner face along a second longitudinal axis, has a second channel structure complementing the first channel structure,
• wherein the hollow-cylindrical portion has a radial cutout through which the elongate body can be inserted into the second channel structure from outside the hollow-cylindrical portion in a radial direction,
• wherein the second coupling element has a closure body, which is configured to close the radial cutout, can be positioned removably in the cutout and completes the second channel structure on a radially internal face,
• wherein the second coupling element also has a securing element, which can be pushed onto the hollow-cylindrical portion to secure the closure body on the hollow-cylindrical portion, and
• wherein the securing element comprises a sleeve and a compression spring, the sleeve being mounted on the second coupling element so as to be axially displaceable and biased the compression spring.
