<p>The device (1) has a rod (2) with a set of ends. A head (5) is ready to fit partially in a groove (22) of a blade (20) i.e. terrace blade. Two arms (11) are arranged in an approximately symmetrical manner with regard to the rod. The two arms are ready to occupy a disassembling position and a fixing position. A lower face is arranged symmetrically with regard to a diametrically thick zone. Each of two thinning zones forms a tilted slope to cooperate with the groove of the blade at the time of rotation of the device from the disassembling position to the fixing position. An independent claim is also included for a method for fixing a blade facing a grooved edge in a mounting rail such as joist.</p> |
