The invention relates to a thread clamping device for lower winding threads on spindles of a ring spinning frame or ring twisting frame. A clamping sleeve is provided between a clamping ring and a radially protruding flange on the spindle which can be axially displaced between a clamping position, which is defined by the position on the clamping ring, and an open position. The clamping sleeve is associated with an actuation device for the axial displacement thereof, which co-operates with radially extending means on the clamping sleeve. The clamping sleeves are associated with elements for fixing the position thereof at least in the clamping position. The aim of the invention is to introduce lower windings into the clamping gap and to improve the removal thereof from the clamping gap. As a result, the actuation elements and/or the radially protruding means are maintained on the clamping sleeve in a radially, elastically touching manner in relation to each spindle axis and are provided with rising sloping surfaces which are radially effective in both relative directions of movement.
