A terminal block for connecting electrical conductors has a first clamping spring element (20) and a second clamping spring element (30) for clamping the electrical conductor. The first and second clamping spring elements (20, 30) are vertically offset from each other, and with an operating element for opening the clamping spring elements against the spring force. A first operating element (40) is provided for the first clamping spring element (20) and a second operating element (50) for the second clamping spring element (30). The first and second operating elements (40, 50) can be actuated independently from each other.
