The invention relates to a connecting terminal for a busbar in a busbar system in which the busbar has an n-agonal cross-section (n >/= 3) with longitudinal undercut acceptor grooves in its outer sides. In a connecting terminal consisting of simple parts and which is easy to fit consists of two terminal sections which can be fitted on the busbar and connected together, can be inserted with securing components in recesses in the busbar and secured transversely to it therein, the terminal sections form a terminal chamber over the outside of the busbar directed transversely thereto and securing screws can be adjusted in the webs of the terminal sections away from the outside of the busbar which clamp terminal sections in the terminal chamber to a line inserted therein with a connection to the outside of the busbar.
