Abstract: Electrical connections for conductors on two spaced apart films are provided by means of a strip of connecting devices. The strip comprises a carrier strip with the connecting devices extending therefrom at spaced intervals. Each connecting device has first and second side-by-side crimp portions, each crimp portion being generally U-shaped. The connecting devices are crimped onto the two films by positioning one film between the arms of the first connecting devices of a section of the strip and the second film between the arms of the second connecting devices. The connecting devices are then crimped onto the film and the carrier strip is removed. A housing for the connecting devices is also disclosed.

Abstract: A bus bar with three phase conductors and one neutral conductor is engageable by an adapter in the shape of an elongate plug designed to connect an external circuit across the neutral conductor and a selected phase conductor. The adapter housing contains two parallel shafts A, B each carrying a resilient contact blade, these blades being retracted into the housing in a disengagement position and being extendible by rotation of the respective shaft through 90.degree.. A locking slide between the two shafts prevents rotation of shaft B until shaft A has been rotated to engage its blade with the neutral conductor whereupon shaft B may be rotated, in one of two axial positions, to bring the other blade into contact with the selected phase conductor whereby shaft A is locked in its engagement position. Shaft A also carries tongue-shaped detents which in its engagement position enter grooves in the bus bar to prevent untimely withdrawal of the adapter.
