A cable gland device for the electric interconnection of electric cables, comprising: - at least a first body made of an electrically insulating material comprising: - at least a first passage channel of at least an electric cable; and - first tightening means (9, 10) of said electric cable inside said first passage channel; - at least a second body made of an electrically insulating material which comprises at least a second passage channel of said electric cable and is coupleable to said first body for the activation of said first tightening means (9, 10); wherein that said second body comprises second tightening means of said electric cable inside said second passage channel; wherein said second body comprises: - at least a first closure element having: - at least a first stretch coupleable to said first body and adapted to activate said first tightening means (9, 10); and - at least a second stretch having said second tightening means; - at least a second closure element coupleable to said second stretch and adapted to activate said second tightening means; wherein said second tightening means comprise at least a yielding regulator element having a first ending part associated with said second stretch and a second free ending part movable towards the longitudinal axis of said first closure element and by the fact that said yielding regulator element extends in the circumferential direction; wherein said first tightening means (9, 10) and said second tightening means are switchable between: - a free configuration, in which said electric cable is movable along said first and second passage channel (3, 6); and - a locking configuration, in which said electric cable is locked along said first and second passage channel (3, 6); wherein said regulator element comprises: - a first side facing said second passage channel and having at least an abutment edging adapted to keep said electric cable in a fixed position with respect to said second stretch in said locking configuration; and - a second side opposite to said first side and having at least a fin with an outwardly protrusion growing from said first ending part to said second ending part, said fin being coupleable with the thread of said second closure element; characterized by the fact that said second side has a plurality of said fins arranged in succession along the longitudinal axis of said first closure element and having growing protrusions relative to each other towards said first stretch. - at least a first body made of an electrically insulating material comprising: - at least a first passage channel of at least an electric cable;
