Abstract: A piece of furniture of modular build-up comprises as basic structural elements a frame and an insert plate to be mounted in the frame compartment by corner fittings. The comer fitting is detachably mounted on the insert plate and comprises at least one laterally accessible receptacle parallel to the plane of the plate for a retaining pin mounted on the frame as well as a locking mechanism for the retaining pin to be arrested in the receptacle.

Abstract: A screen connector for engaging a cable, including an uncovered cable screen, positioned on a plate member is disclosed. The screen connector includes a clamp clip having at least two clamping legs which are spring-mounted relative to one another. The legs of the clamp clip encompass the plate member or busbar by lying opposite one another on the outside, whereby they engage the busbar from below, preferably by a coupling hook. The screen connector also includes a guide press piece having an outer and inner guide surface which slides along outer and inner guideways of the clamping legs when the guide press piece is moved to enclose the clamping legs. The guideways are shaped on the clamping legs in such a way that the clamping legs can be spring-mounted relative to one another when the guide press piece is in an upper initial position, and consequently can be locked onto the busbar in a perpendicular direction to the upper side of the busbar by means of their coupling hooks.
