Abstract: A hinged cover assembly for a connector block comprising an insulating lid portion having a pair of flexibly attached pin hinges at one end thereof is presented. The pin hinges are insertable in and form a friction fit with oppositely disposed spaces on each fanning strip of the connecting block. Preferably, the pin hinges consist of a pair of labels interconnected by straps which double back over themselves and a pair of pins to form a strong, flexible strapped pin hinge. The straps and labels may be separate pieces or formed as a one-piece construction.
