Abstract: A distributing device made up of a set of modular elements for use with multiconductor cables. Each of the modular elements includes symetrically arranged pairs of conductors. Each pair of conductors includes an incoming conductor to be connected to one wire of the multiconductor cable and an outgoing conductor to be connected to a jumper wire. The two conductors are normally shorted together by a spring contact. A plug is provided which by partial insertion allows connection to the conductors of a pair without interrupting the connection between the two conductors, and upon complete insertion, pushes the spring contact away from the conductors to interrupt the connection between the two conductors.

Abstract: A fastening and locking device which can rapidly join two elements together in a secure manner. The device comprises a male part on one of the elements and a receiving channel for the male part on the other of the elements.
