The handles are of the type that are fixed to the square-section shaft of the lock by means of a radial screw. According to the invention the end of the square-section shaft (1) has a threaded axial hole (3) for a securing screw (8) of an elastic laminar element (4) folded into a "U", the core of which contains a passage hole for the screw (8) and its arms (5) are located in separate recesses (6) of two opposing faces of that shaft (1). The bottom of the recesses (6) has a "V" shaped section and there is a longitudinal groove (9) along the edge. The radial screw (10) has a protuberance (11) which elastically arches the arm (5) and afterwards pierces it and bites into the walls of the groove (9). This arrangement axially and radially locks the handle (2). |
