Abstract

An overhead cable indicator ball (2) is defined by two half-balls (3) coupled in a reciprocally sliding manner to shift at least one pair of clamping elements (13a, 13b) between a clamping position and a release position of at least one overhead cable (2); the clamping elements (13a, 13b) being provided one with at least one guide (23) and the other with at least one coupling member (22) slidingly coupled to the guide (23) itself.
