A hydraulic fastening device, for securement of two components, for example, securement of teeth to a bucket on earthmoving or mining equipment. Each component (29 and 51) has an orifice (50 and 52) therein adapted to be substantially aligned. A body member (26) is inserted in the aligned orifices (50 and 52). A control means (34) is then operated to move at least one protrusion (40 and 41) to protrude from the body (26) and to fasten the components (29 and 51). This is achieved by hydraulic operation and connection of a fluid conduit (32) between the control means (34), e.g. a grease nipple, and the protrusions (40 and 41).

La présente invention concerne un dispositif de fixation hydraulique, permettant de solidariser deux éléments, par exemple de fixer une dent sur un godet d'engin de terrassement ou d'engin minier. Chacun des éléments (29 et 51) présente un orifice (50 et 52) réalisé de façon à pouvoir sensiblement aligner les orifices. Une partie du corps (26) étant insérée dans les orifices alignés (50 et 52), la manoeuvre d'un organe de commande (34) permet alors de provoquer la sortie de l'un au moins des ergots (40 et 41) du corps (26) de façon à fixer les éléments (29 et 51). Cette opération est réalisée par commande hydraulique et raccord d'un conduit de fluide (32) entre l'organe de commande (34), un raccord graisseur par exemple, et les ergots (40 et 41).
