A pin strip is disclosed for a multi-row plug connector for transmitting small signals with low crosstalk in data processing systems with intermeshed ground planes which are in each case arranged between signal planes. Between at least one row of pins which forms a signal plane and an adjoining row of pins which forms a ground plane there is a shield plate spring clamped in position whose edges are bent inwardly and which contact all the pins of the ground plane. An insulating film is provided to insulate the plate from the signal plane pins.
