Abstract: A strip is provided with a series of housings for a like number of terminals to which conductor wires accede thrust by a tool in order to establish a connection, by means of displacing the conductor wires over the terminals. Each housing or chamber is independent of those adjacent, the separation being constituted by means of transversal partitions, which makes possible the pouring of a sealing gel into the respective housing chamber up to a level which is at a height lower than the entrance step of the conductor wires and above the edge of the terminals, with the objective that both said terminals and the connections thereof with the conductors be immersed in the sealing gel in order to prevent oxidation on the connections.
