Terminal for detecting an optically invisible network, installation comprising such a detection terminal, and method for detecting an optically invisible network

A detecting terminal for detecting an optically invisible network, the detecting terminal including:

• a fastening element intended to be fastened in or on a support,
• electrical connection means for the connection of propagation means arranged to propagate an electrical signal along the optically invisible network, the electrical connection means including a connection point for the electrical connection of an electrical signal source, such as an electrical signal generator,
• grounding means intended to be grounded, and
• a protection element comprising at least one electrically conductive portion, the protection element being movable relative to the fastening element between a first position wherein the protection element covers at least partially the electrical connection means and the electrically conductive portion is in electrical contact with the electrical connection means and is electrically connected to the grounding means, and a second position wherein the electrically conductive portion is electrically insulated from the electrical connection means.
