A hydraulic fastening device for securement of two components together, each component having an orifice or cavity at least partly there through adapted to be substantially coaxially aligned, the fastening device including a body member adapted to be inserted substantially within the orifice or cavity of each component when substantially coaxially aligned. The body member includes a main body section and a hydraulic manifold section with a fluid conduit within at least the manifold section and containing a fluid therein. The device further includes at least one moveable protrusion means in fluid contact with the fluid, adapted to protrude from the manifold section; and control means to control the movement of the or each protrusion means. The arrangement is such that, upon operation of the control means, the or each protrusion means is moved between a protruding position and a retracted position and when in the protruding position the two components are adapted to be fastened or locked together.

L'invention concerne un dispositif de fixation hydraulique permettant de fixer deux composants, chacun présentant un orifice ou cavité au moins partiellement conçu pour être aligné de manière sensiblement coaxiale. Le dispositif de fixation comprend un corps conçu pour être inséré sensiblement dans l'orifice ou cavité de chaque composant lorsqu'il est aligné de manière sensiblement coaxiale. Le corps comprend un partie principale et un collecteur hydraulique doté d'un conduit pour fluide et contenant un fluide. Le dispositif comprend en outre au moins des éléments saillants mobiles en contact fluidique avec le fluide, conçus pour faire saillie à partir du collecteur et des moyens de régulation permettant de réguler le mouvement de chaque élément saillant. Le système est conçu de manière que, pendant le fonctionnement des moyens de régulation, chaque élément saillant est déplacé entre une position saillante et une position rétractée. Une fois que les deux composants sont en position saillante, ils peuvent être fixés ou bloqués ensemble.
