Abstract: An apparatus for installing between a pair of spaced terminals a wire having a conductive core and an insulating sheath surrounding the core and interrupted at spaced stripped regions has a head defining a passage having an outer end, a guide element on the head at the outer end forming a passage alignable with the head passage, and a supply for feeding the wire along the head passage and the guide-element passage. A cutter on the head at the outer end can sever through the core in the stripped regions between the head and the guide element and the guide element can be pivoted on the head about an axis transverse to the guide-element passage for directing the passage at any of a plurality of different angles to the horizontal and vertical.

Abstract: A marker plate construction for use in terminals, particularly, serially disposed multiple terminals as used in switching appliances. Known marker plates are linked into strips and have to be individually separated from the strip in cases when the juxtaposed terminal blocks have different widths. The marker plate strips according to the invention include tear-off connectors between the individual marker plates which are extensible, or are of variable length in such a manner that the cutting of the marker plate strip during the insertion of the individual marker plates at separate terminal blocks is eliminated.

Abstract: Electrical distribution and/or connection devices include an electrically connecting bridge having two contact limbs with respective contact points for the connection of respective electrical conductors. The contact points may comprise spring clamps. The devices may be formed for mounting in line on a rail and may be formed for the connecting bridge of adjacent devices to be interconnected by a removable bridge component which has two contact limbs for engaging the respective said connecting bridges at web portions thereof disposed between the respective contact points.

Abstract: A screwless connector or coupling for electric leads, having a clamping spring located in an insulating material housing and retained therein, forming with a contact bridge at least one conductor clamping position, wherein the contact bridge and the clamping spring are substantially flat and are interconnected at a common end region to form a self-supporting unitary structure, the contact bridge being provided at a point spaced from the point where the contact bridge and clamping spring are connected with a plurality of conductor bush openings arranged in spaced juxtaposition, the clamping spring in the region of each contact bridge bush opening having at least one clamping edge located behind the contact bridge in the insertion direction of the conductor.
