<p>A system for holding together parts of a construction until the moment of separating the parts from each other, comprises at least two sections (5,6) having abutting faces and a tension element (7) cooperating with supporting means, said tension element being provided on said sections holding said sections together under pre-tension, and breaking means (11) for breaking said tension element so as to separate said sections (5,6), said tension element (7) is wound around said supporting means forming a closed loop bundle that crosses the parting lines of said sections, whereby the strength of the bundle equals at least the pre-tension required to hold said sections together. <IMAGE></p> |
