Patent ID: 8128032

Claim:
An aircraft wing having a longitudinal span and consisting of at least two wing elements positioned end to end, a first wing element being secured, dismantleably, to an adjacent second wing element using at least one coupling means, wherein said coupling means comprises: a male coupling piece borne by said first wing element substantially parallel to said longitudinal span of said wing, said male coupling piece having a mounting end for mounting on said wing element and a free end and exhibiting an upper face and a lower face which are separated from one another and face outward away from one another, a first of said faces being substantially planar, a second of said faces comprising a relief running longitudinally with a substantially V-shaped cross section, and said first and second faces being inclined with respect to one another so that said first and second faces converge toward one another toward said free end thereof; a female coupling piece borne by said second wing element substantially parallel to said longitudinal span of said wing, said female coupling piece having a mounting end for mounting on said second wing element and a free end and exhibiting an upper face and a lower face which are separated from one another and positioned facing one another, a first of said faces being substantially planar, a second of said faces comprising a relief running longitudinally with a substantially V-shaped cross section, of a shape that complements the shape of said V-shaped cross section of said relief of said second face of said male coupling piece, and said first and second faces being inclined with respect to one another so that said first and second faces diverge from one another toward said free end, with an inclination with respect to one another which is the complement of an inclination of said mutually-inclined faces of said male coupling piece, and retaining means capable of holding said two coupling pieces in a coupled position with said respective cooperating upper and lower faces thereof kept firmly pressed together, by virtue of which, when said two coupling pieces are in said coupled position said coupling pieces are immobilized relative to one another against any relative rotation.
