Abstract

Structure de type paille, comprenant une première moitié (1), dont un côté est en retrait pour former une première ouverture (11) ; et une seconde moitié (2), dont un côté est en retrait pour former une seconde ouverture (21) qui peut être raccordée à la première ouverture (11). La première ouverture (11) et la seconde ouverture (21) sont raccordées pour former un canal d'écoulement (3). Un espace (4) est présent à l'endroit où la première moitié (1) et la seconde moitié (2) sont reliées. Un premier élément de fixation (14) est présent sur au moins une extrémité de la première moitié (1). Un second élément de fixation (24), qui peut être relié au premier élément de fixation (14), est présent sur au moins une extrémité de la seconde moitié (2). Le premier élément de fixation (14) et le second élément (24) sont disposés sur la surface circonférentielle externe à l'extérieur de l'espace (4) entre la première moitié (1) et la seconde moitié (2). Un bord contigu (25) disposé dans la direction longitudinale de la seconde moitié (2) est présent sur au moins une extrémité de la seconde moitié (2). Lorsque la première moitié (1) et la seconde moitié (2) sont reliées, le bord contigu (25) protège l'espace (4) entre la première moitié (1) et la seconde moitié (2), ce qui permet d'obtenir des effets antifuites et d'étanchéité à l'air.
