A latch needle (1) has a latch spring (19), which assumes the width of the latch slit (5) in the vicinity of the latch seating (18). However, the latch spring (19) is embodied to be narrower on both sides of this section (25). By means of this, premature wear of the latch or spring in the area of the latch seating device (18) is counteracted on the one hand as is, on the other, the obstruction of the latch slit (5) by dust or dirt. The narrower sections (26, 27) of the latch spring (19) define a passage together with the inner face (8, 9) of the slit walls (6, 7), through which foreign bodies, such as fiber remnants, dust or the like can be conveyed from the upper needle side (11) in the direction toward the needle back (12). In contrast to conventional latch needles, needles (1) of this type of construction show reduced wear, a reduced susceptibility to becoming soiled, and therefore increased dependability.
