ABSTRACT OF THE DISCLOSURE The invention is concerned with a protective cable head for a telephone exchange distributor, which includes a plurality of modular connection units comprising a base of insulating material carrying at least one earthing component and pairs of connection members disposed both at the rear of the base, next to cables which are to be connected, and at the front of the base, next to application jumpers, the units being arranged on a channel for passing through the cables which are to be connected. The cable head of the invention is characterized by at least one protection module for each connection unit which can be plugged into the base from the front. The module consists essentially of a body of insulating material having two side-housings for receiving two lightning arresters, and two pairs of wrap-around contact components mounted on the body for establishing electrical contact between the front and rear connection members arranged face to face and for establishing electrical contact with the earthing component. Each pair of contact components includes means for electrically mounting a lightning arrester and for retaining the lightning arrester in its housing, and means for reinforcing the clamping of tails of the lightning arrester upon the plugging of the module into the base.
