As is shown in the Figures 1 to 7, the connecting body 1 is embodied having a substantially elongated, op- tionally square, body 2 to be completely driven into the bone pieces (not shown) . At both sides, the body 2 has turned ends 3 and 4. The embodiment variants shown in the Figures 1 to 7 additionally have a sharp edge 5 provided on the body 2 between the ends 3 and 4. The body 2 may further be provided with a tooth 6 pressed out from the surface of the body, preferably pointing in the direction opposite to the direction into which the sharp edge 5 is pointing. This is shown in Figure 1. Figure 3 shows the embodiment in which the body 2 is provided with one or more perforations 7. Further, the body 2 may be provided with a biocompatible coating. The embodiment variants shown in the figures are distinguished by the fact that the embodiment shown in Figures 1 and 3 are shaped like an S, the embodiment shown in Figure 2 is shaped like a C, while the embodiment shown in Figure 4 has an undulating body 2. Figures 5 and 6, show variations on the embodiment shaped like an S and a C, respectively, while Figure 7, relates to an intermediate form between the S or C shape and the completely undu- lating body 2 shown in Figure 4.
