The device comprises a slide (3) so profiled as to be insertable in a support (2) in a slidable and coaxial manner with respect to an elongate element (1) and in intimate contact with the latter. This slide has two lateral lips (5) adapted to cooperate with ramps for clamping the slide and formed in the support (2), the lips and the ramps being inclined to the axis of the elongate element (1). The lips (5) are advantageously rounded and define an intermediate constricted part thereby achieving a self-clamping of each lip (5) of the slide (3) in the associated ramp of the support (2). The device supports an extremely high assembly prestressing without deforming or breaking, even when the prestressing is increased in an exaggerated manner, this being achieved with an overall size which is smaller than a screwed assembly of elements of a cross-shaped structure. Various applications in particular in the connection of a spinal osteosynthesis rod with a pedicular anchorage element.
