We have observed zigzag disclination lines in uniaxial thermotropic and lyotropic nematic liquid crystals. Our samples are placed in round and flat capillary tubes. This confined geometry and the instability of the lines under three-dimensional perturbations are responsible for the observed shape.Nous avons observé des lignes de disinclinaison en zigzag dans des nématiques uniaxes thermotropes et lyotropes. Nos échantillons sont préparés dans des tubes capillaires ronds et rectangulaires. Cette géométrie confinée et l'instabilité des lignes vis-à-vis de perturbations tridimensionnelles sont responsables de la forme observée
