An improved ploughshare holder body is characterised in that it includes tension springs 9 which act on a connection piece 4 of the ploughshare holder body, and in that this connection piece 4, the cross-section of which is in the shape of an inverted "U", is articulated at one of its ends onto the upper part of a support piece 1, connected to the chassis 2 of the plough, whereas the ends of the springs 9, one on each side of the inverted U-shaped piece 4, are articulated onto the lower area of the support piece 1, and onto a tensioner located on this inverted U-shaped piece 4. <IMAGE>
