Les lamelles sont associées à un élément d'expansion (24) doté d'une tige (22) pouvant être axialement rétractée dans un orifice de passage (14) pratiqué dans le corps d'obturation (16) et d'un corps d'expansion (26) se trouvant au niveau de son extrémité opposée au corps d'obturation et se trouvant, en position initiale dans la zone des extrémités libres des lamelles, ledit corps d'expansion étant tiré entre les lamelles lors de l'introduction de la tige (22) à l'intérieur de l'orifice de passage (14) du corps d'obturation (16) et écartant lesdites lamelles de façon radiale. Contre le corps d'obturation (16) se trouvent, décalés de façon radiale l'un par rapport à l'autre en direction circonférentielle, un certain nombre de fins volets d'obturation (36), correspondant au nombre d'interstices (30) formés entre les lamelles étendues (18) de l'élément d'expansion (12), lesdits volets s'étendant vers l'extérieur en formant des secteurs, et pouvant pivoter sur le corps d'obturation (16) dans un position dans laquelle les volets d'obturations (36) se trouvent chacun sur un interstice (30) associé situé entre des lamelles (18) voisines de l'élément d'obturation (12).
