  • connection accessory according to the invention is advantageously compatible with the various existing combs, whether unipolar combs or whether they are multipolar combs.
  • the plane of at least one of the pins that comprises the connection accessory according to the invention is oblique to the cable electric, and, for example, this is the case for both of its two pins.
  • this electrical cable is advantageously inclined relative to the rear face of these electrical devices, and, therefore, relative to the bottom of the envelope in which these are arranged and / or to the wall on which this envelope is possibly reported.
  • connection accessory according to the invention is found thus further advantageously facilitated, in particular when the space available between the support sleepers and the bottom of the enclosure and / or the wall concerned is measured.
  • the electric cable advantageously knows, from one to the other of these electrical devices, a more natural and more short.
  • these electrical devices 10 are modular electrical equipment, such as, for example, circuit breakers.
  • connection terminal 16 in this case their lateral face 15 upper part, and on the other hand, onto it, one of the the other, two connection terminals 16, namely, one of phase and one of neutral, offset from each other both perpendicular to the main faces 11 only perpendicular to the rear face 12.
  • bus bars 18 are also well known in themselves, and nor will they therefore be described in detail here.
  • bus bars 18 are unipolar.
  • connection accessory 23 In a manner known per se, it is implemented, from one to the other of the two electrical equipment 10 concerned, at least one connection accessory 23.
  • connection accessories 23 are provided, one for connecting one of the connection terminals 16 of one of the electrical devices 10 to the terminal corresponding connection 16 of the other of these, and the other to connect one to the other the other connection terminals 16 of these electrical devices 10.
  • connection accessories 23 are identical to each other.
