Abstract:
1. A method for connecting two elongated elements, having circumferential outer surfaces, by a connecting member incorporating a spiral shaped winding spring having a center line, the method comprising the steps of screwing the spring on and around the elongated elements at a connecting place disposed between the elongated elements by rotation on the center line while axially expanding the spring by contact with the circumferential outer surfaces of the elongated elements; the winding spring having a center line and at least one winding having a diameter smaller than a largest transverse dimension at a connection place determined by the elongated elements to be connected, the winding spring having a position at a starting point wherein said center line is disposed at an angle relative to the elongated elements, the winding spring being moved by a screwing movement from said starting point toward said elongated elements, wherein said screwing movement is continued until at least one winding is diametrically expanded.
