A removable closure member for closing a cylindrical opening having a circumferential slot therein, the closure member formed of a plug body having a top surface (90) and an external cylindrical surface (80), a first and a second leaf (192, 194) each having an outer substantially semi-cylindrical edge, a first end portion of each leaf (192, 194) being pivotally secured to the plug body permitting each leaf to be pivoted between a retracted position and an expanded position in which the outer edge of each leaf is receivable within the circumferential slot (76) in the cylindrical opening and a plug holder removably attachable to the plug body top surface and having a rotatable portion for pivoting the leaves between their retracted and expanded positions.
L'invention concerne un élément de fermeture amovible destiné à obturer une ouverture cylindrique dotée d'une fente circonférentielle. L'élément de fermeture est formé d'un corps de bouchon présentant une surface supérieure et une surface cylindrique extérieure, d'une première et d'une seconde aile comportant un bord extérieur sensiblement semi-cylindrique. Une première partie de chaque feuille est fixée de manière pivotante au corps de bouchon, ce qui permet à chaque feuille d'être pivotée d'une position rentrée à une position déployée dans laquelle le bord extérieur de chaque feuille peut s'insérer dans la fente circonférentielle de l'ouverture cylindrique. Un support de bouchon peut en outre se fixer de manière amovible à la surface supérieure à la surface supérieure du corps de bouchon, et comporte une partie rotative destinée à pivoter les ailes de la position rentrée à la position déployée, et vice-versa.
