The flat components (2) have rectangular recesses (1), corresp. to a collector bar (3) of rectangular cross-section. Pref. at one end section the bar has a form stop (4), while a releasable stop is fitted to its other end section. Alternatively both end sections are fitted with releasable stops. The releasable stops are typically in the form of insertable clamps. An end section allocated to the releasable stop may comprise transverse teeth (7) with a triangular cross-section, to which correspond triangular teeth of the clamps.
