Un moyen de fixation (10) est constitué par une tige allongé (12) présentant une extrémité distale (18) partiellement filetée et une extrémité proximale (14) sur laquelle est formée une partie conique (20). Deux garnitures (28) de configuration identique peuvent être positionées sélectivement autour de la surface extérieure de la partie conique (20), lesdites garnitures (28) ayant des parois d'épaisseur sensiblement uniforme, et les surfaces desdites parois intérieures et extérieures (30, 32) étant coniques et courbes. Les surfaces des parois intérieures (30) sont calibrées et ont une forme leur permettant d'épouser intimement et sensiblement recouvrir la surface extérieure de la partie conique (20) lorsque les garnitures (28) sont mises en place. Un élement (36) du moyen de fixation peut être fixé sélectivement sur la tige (12) et comporte un perçage traversant (42), qui définit une surface intérieure tronconique, calibrée et configurée de manière à pouvoir être reçue par glissement sur les surfaces extérieures des garnitures, et à ètre retenue par friction sur celles-ci.
