A shock absorber for a safety line apparatus, characterised in that it comprises two rods (2) slidably associated to one another, the rods (2) each exhibiting a first end (2a) and a second end (2b), the first ends (2a) being connectable to a cable of a safety line apparatus, the rods (2) further exhibiting respective prevalent longitudinal development axes (B) which are substantially parallel to one another, the first ends (2a) moving in reciprocal distancing/nearing when the second ends (2b) move respectively in reciprocal nearing/distancing; a dissipation organ (10) arranged between the second ends (2b) of the rods (2) and activatable by nearing the second ends (2b) in order to brake a distancing sliding action of the first ends (2a) of the rods (2), the dissipation organ (10) being plastically deformable to pass from a first configuration in which the dissipation organ (20) exhibits a maximum length to a second configuration in which the dissipation organ (10) exhibits a minimum length.
