ABSTRACT:
A protection module for connecting blocks is intended notably for at least one line wire of a telephone system and comprises a case having a ground terminal, an input terminal and an output terminal for each line wire, and a first lightning arrester having a first terminal connected to the ground terminal and a second terminal clamped resiliently between two extensions of the line terminals, respectively. Another lightening arrester has a first terminal connected to the ground terminal and a second terminal clamped resiliently between two extensions of the other pair of line wire terminals. An orifice registering with a third pair of terminals parallel to the other pair of line wire terminals is adapted to guide a detachable element which comprises an insulating portion adapted to be fitted between the terminals of the third pair of the lightning arresters and each extension of the pair of output terminals.
