The arrangement is for holding together two thin-walled parts (13,14) and incorporates at least one screw (15), and at least one flat part which through a bent part is connected with a further flat part, which in turn is connected with a bridge part and a downwardly bent distance leg. - The bridge part is provided with two downwardly bent springs (5,6) which in their lower parts are formed into a thread path (7,8) and on fitment engage the screw threads. The screws through their elasticity snap-engage over a thread top to engage in the next thread. By active action of the rigidity and thereby the elasticity of the spring snap force, it is possible to determine the tightening torque. |
