A connecting terminal (1) having an insulating-material housing (2) and having at least one spring clamping unit with a clamping spring (4) and a busbar section (3), in the insulating-material housing (2), is described. The clamping spring (4) has a contact section (6) and a clamping section (8) which is designed to clamp an electrical conductor against the busbar section (3). The clamping spring (4) has an operating section (13) which originates from the clamping section (8), extends away from the direction of the spring force, which acts on the clamping section (8), of the clamping spring (4) and is aligned to be acted on by an attachment element (16, 31, 33, 39) such that the operating element (16, 31, 33, 39) can be engaged with the operating section (13) in order to exert a tensile force, which acts on the operating section (13) in the opposite direction to the spring force when the operating element (16, 31, 33, 39) is moved, in order to open the clamping spring (4).
