An arm coupling element for windscreen wiper that solves the problem entailed by the multiplicity of fastening device coupling elements and arms. The present invention provides a universal device that allows the installation by the user, in a simple, easy and quick way. The present invention comprises a central body (1), three transversal coupling bores (2,3,4) of different dimensions set on the central area of said main body (1) that presents the lower part of its lateral walls cut away allowing direct access to said transversal coupling bores (2,3,4), two lateral bulges (5,6) located at both lateral walls of the main body (1), being one in each of its ends, two flexible adjustment pawls (7,8) located transversally on the upper part of the main body (1), a slack reducing moving part (9) located at the end of the main body (1) over which rests the windscreen wiper's arm hook (101), two transversal slots (10,11) adjacent to the central hole (3) and two moving locking bulges (12,13) located at the end of the main body (1) between which rests the windscreen wiper's arm hook (101). <IMAGE> |
