  • the fuse 116 is pulled for its extraction, the upper end of the receptacles 114, indicated with the reference 114b in Figure 7, leans against the ribbings 107, thus preventing the slipping of the receptacles 114 out of the holder.
  • a different arrangement of the pins 105 and of the sleeves 106 in the holder 101 may be provided and two openings in the central portion 101c will be provided in order to allow the wires connected to the receptacles to pass.
  • the holder according to the invention can be also applied, without any substantial change or variation, to the electrical connection of two poles of an electric system. by substituting the fuse with a plate plug which may be joined or separated.
