PURPOSE: To alleviate a maintenance work such as replacement of a fuse or the like by providing lightning protective elements to be connected to a plurality of sets of modular jacks and slit terminals.
CONSTITUTION: Two modular jacks 6a, 6b are multiply connected at contacts, and connected to 1 slit terminal 20 and a lightning protective element 26. Similarly, the contacts are multiply connected together with the other two modular jacks 6c, 6d, and further connected to the terminal 20 and the element 26. It has a ground 19 of the element 26, a commercial power source plug 10 and a plug socket 17. Thus, when a subscriber's lightning protective device and an extension lightning protective device are mounted in a hole device such as a telephone set or the like, the modular jacks of the device are employed in case the connecting terminals of the home device are of modular jacks. If they are of slit terminals, the slit terminals are employed to be easily mounted.
