A terminal clamp is described. The terminal clamp includes a housing, a clamp pocket arranged in the housing into which a conductor to be clamped can be inserted, the clamp pocket having a base wall, and two side walls which are opposite each other, which extend away from the base wall, and which form a conductor guide channel, the conductor guide channel having, at least in regions in the longitudinal direction thereof, a cross-section which continually narrows towards the base wall, and at least one clamping spring protruding into the clamp pocket for clamping the inserted conductor in the clamp pocket.
