What is described is: a spring-loaded connection terminal (3) comprising a busbar piece (5) which has a base surface (6) and side walls (7) emerging laterally from the base surface (6). Mutually opposite side walls (7) delimit a receiving area (35) on both sides. The spring-loaded connection terminal (3) has a terminal arrangement for the terminal connection of an electrical conductor at an associated clamping point with at least one clamping spring (8), which is operatively connected to the busbar piece (5). At least one current bar (25, 25a, 25b) which is separate from the busbar piece (5) is introduced into the receiving area (35) of the busbar piece (5) and arranged in the receiving area (35) so as to form a clamping surface for the terminal connection of an electrical conductor.
