Abstract: Disclosed is a device for fastening together two components to be joined, the device including a connection rod including two ends, a first end being fastened to a first component, the second end extending through the second component, the second end being having a bearing surface. This device is characterized in that it includes a clamping wedge which is associated with the second component and which is movable relative to the second component along an axis which is not parallel with the longitudinal axis of the connection rod and which is provided in an inclined plane, the wedge being interposed between the bearing surface of the second end of the connection rod and the surface of the second component so that, during its movement, the wedge, by way of its inclined plane, applies an axial constraint to the connection rod and ensures that the two components are fastened together.
