2. Anti-fall safety system according to claim 1, characterised in that said anti-fall safety system comprises at least one pair of said engagement elements which are placed in correspondence of opposite ends of said elongated means, one engagement element of said pair of engagement elements being intended to engage in correspondence of said first component at a first engagement point and another possible engagement element of said pair of engagement elements being intended to engage in correspondence of said second component at a second engagement point, following said engagement by means of said engagement elements said elongated means preventing the detachment or the displacement beyond a pre-set maximum limit of said first component with respect to said second component in case of failure, breaking or detachment of one or more of said reciprocal retaining means.

3. Anti-fall safety system according to claim 1, characterised in that said at least partially flexible elongated means in the form of a cable is a multi-strand cable, even more preferably a steel multi-strand cable or a cable of elastomeric material.

4. Anti-fall safety system according to claim 1, characterised in that said elastic means is a spring.

5. Anti-fall safety system according to claim 1, characterised in that said elastic means is an elastic element of rubber or of elastomeric material or of an equivalent at least partially elastic material.

6. Anti-fall safety system according to claim 1, characterised in that the length of said elongated means is at least equal to, preferably greater than the maximum distance between said first engagement point and said second engagement point when said first component is in said opening position.

7. Anti-fall safety system according to claim 1, characterised in that said elongated means is adapted to slide at least in correspondence of or in proximity to one of said engagement elements, preferably in correspondence of or in proximity to both said engagement elements.

8. Anti-fall safety system according to claim 7, characterised in that at least one portion of said elongated means is adapted to slide within an interspace or a hiding seat obtained within profiled elements constituting said first component or said second component

9. Anti-fall safety system according to claim 7, characterised in that said elongated means is adapted to slide along a sliding length which is greater than or equal to the maximum distance between said first engagement point and said second engagement point when said first component is in said opening position.

10. Anti-fall safety system according to claim 1, characterised in that a first engagement element of said engagement elements engages in correspondence of said first fixing element which is adapted to be applied in correspondence of said first engagement point and a second engagement element of said engagement elements engages in correspondence of a second fixing element which is adapted to be applied in correspondence of said second engagement point, said second fixing element being shaped in the form of a plate provided with a passage which is intended to allow the passage of said elongated means but shaped with a size of the passage such as to prevent the passage of said engagement element, which engages on said second fixing element in correspondence of said passage.
