The present invention relates to a device for locking
ring holders of movable ring rails of ring spinning and
twisting machines and, more speci?cally, refers to such
prises guiding means 1, for instance in form of guiding
rods, attached to a ring rail 4, and along which guiding
rods the individual ring holders 2 are axially displaceable
by means of guiding sleeves 3. Inter-posed between each
ring holder 2 and the movable ring rail 4 is a magnet 5.
In the particular embodiment shown in FIGS. 1 and 2,
