<p>An anti-effraction safety system for a door or window frame (10) comprising a fixed frame (12) and a mobile frame (14), in which the mobile frame (14) comprises at least one sectional element (20) with a longitudinal groove (32) with two undercut portions (40) set on opposite sides of a longitudinal central opening (42) and in which at least one transmission rod (30) slidably engages said groove (32) and can be displaced in a longitudinal direction by means of a control handle (26). Fixed to the transmission rod (30) is at least one closing element (34) co-operating with a complementary detent (36) fixed to the fixed frame (12). The transmission rod (30) has two through openings (54, 56) both open on respective longitudinal edges of the rod (30). The closing element (34) comprises two separate complementary parts (60, 62) fixed to one another, in which each of said separate parts (60, 62) engages a respective through opening (54, 56) of the transmission rod (30) and has a respective tenon (64, 72) that slidably engages in a longitudinal direction a respective undercut portion (40) of the groove (32).</p> |
