Abstract
Abstract Electrical connecting device comprises a generally V-shaped member having wire receiving slots extending into corresponding side edges which are adjacent to the bight of the V. The plate sections of the V are preferably kinked in alignment with the slots. Upon insertion of a wire, the plate sections are resiliently stressed by the wire in a manner to cause them to move towards each other. Additionally, the individual plate sections may be flexed by stressing of the kinked sections in the manner of a cylindrical spring.
