Electrical connecting terminal

An electrical connecting terminal (1) having an insulating material housing (2) and having at least one spring clamping connection in the insulating material housing (2), the at least one spring clamping connection having a cage tension spring (3) having a bearing limb (5) which rests on a busbar section (4), a rear spring bow (6) which adjoins the latter and an operating limb (7), the operating limb (7) having, on a clamping section which is bent around in the direction of the busbar section (4), a window cutout (8) through which the busbar section (4) is led and the lower crosspiece (9) of which forms a clamping point for clamping an electrical conductor (23) between the crosspiece (9) and the busbar section (4), and a lug (16) projecting forward and outward away from the operating limb (7) in the direction opposite to that of the rear spring bow (6), wherein each spring clamping connection has an operating lever (12) which is pivotably mounted in front of the clamping section of the operating limb (7) of the cage tension spring (3) in a manner adjoining the lug (16) and has a support (18) which is oriented to rest on the lug (16).
