ABSTRACT:
The buckle comprises a tensioning lever (2) on which there is hinged an attachment element (14) to which there is fixed a pulling rod (13) having a threaded part passing through the attachment element (14) and retained on the latter by a button (22) screwed onto the end of the pulling rod (13). By rotating the button it is possible to adjust the active length of the pulling rod. The pin (b 30) for hinging the attachment element (14) serves at the same time as a means for locking the rod (13).
