A device for anchoring to a shutter (11) the free end (12) of a flexible element (13) associated with an actuator (15) for moving the shutter (11), the device (10) comprising an engagement terminal (16), which is rigidly fixed to the free end (12) of a partially flexible chain (14), and a complementary engagement block (17), which can be coupled to the engagement terminal (16) and is rigidly fixed to the shutter (11). The anchoring device (10) allows fine adjustment of the distance of the engagement terminal (16) from the chain, so as to adjust in an optimum manner the closure of the shutter (11) on the casing (11a). The engagement block (17), by way of mutually opposite elastically deformable wings (33), allows quick and easy engagement and release of the engagement terminal (16) according to requirements. The anchoring device (10) allows to avoid the sudden collapse of the chain (14) and the consequent uncontrolled closing of the shutter (11). |
