An inventive heddle for jacquard machines essentially consists of fiber-reinforced plastic material, whereby the thread eye is formed by a mail (12). The heddle body comprises two legs (3, 4). Between the relatively wide thread eye region (5) and the legs (3, 4), ramp sections (6, ) are provided, which sections have a length that is greater than the length of the thread eye (1). Preferably, the length is greater than twice the longitudinal extension of the thread eye. In most cases, said length is between 10 and 30 mm. As a result of this measure, the wear of the plastic material in the vicinity of the thread eye (13) is kept minimal enough that neither any damage to the stiffening fibers (22) in the body of plastic material nor any damage to the warp threads needs to be feared.
