A device for the selection of needles in circular stocking knitting machines, comprising a lower needle (or jack) having radial deflection for each needle on the cylinder of the said machine. Selection actuators are provided for the control of the lower needles. Each lower needle includes two components: an element oscillating between an inoperative position and the operating, vertically movable position in order to control the corresponding needle and to follow the courses of upward and downward movement cams; and a toothed element which is arranged facing the oscillating element, capable of oscillations with same, but prevented from moving vertically. The toothed element always remains at the level of the selection actuators even when the oscillating element moves vertically.
