Osteosynthesis clip

An osteosynthesis clip having an overall U-shape, comprising:

• at least two anchor bars corresponding to two vertical bars of the U shape, each anchor bar comprising a distal end, configured to be inserted into a bone element, and a proximal end;
• and
• at least one connecting bar, corresponding to a horizontal bar of the U shape, connecting together the respective proximal ends of the two anchor bars, said connecting bar comprising at least one longitudinal opening splitting it into two opposite side walls connected together at the ends thereof, deformable in a plane P containing the connecting bar and perpendicular to a plane containing the U-shaped osteosynthesis clip, such that the longitudinal opening is adapted to assume a closed configuration, in which the two anchor bars are substantially parallel to each other and said two side walls are brought close to each other such that a distance between the two proximal ends of the two anchor bars has a value L1, and at least one open configuration, in which central regions of said two side walls are spaced apart from each other on either side of said longitudinal opening, and the distance between the two proximal ends of the two anchor bars has a value L2 strictly lower than L1;
• wherein said osteosynthesis clip further comprises a compression piece having at least one active portion, a cross-section of which in a plane A of said compression piece has an overall oval shape, said compression piece being housed within said longitudinal opening with its plane A coinciding with said plane P and at least one part of an outer face of its active portion in contact with at least one part of inner faces of said two side walls of the connecting bar, said piece being adapted to undergo a rotation about an axis B passing through the center of said oval shape of said active portion and perpendicular to said plane P, thus causing said longitudinal opening to move from its closed configuration to its open configuration, and vice versa.
