Using an analytical model for the Cosmic Microwave Background anisotropies produced by textures, we compute the resulting collapsed three-point correlation function and the rms expected value due to the cosmic variance. We apply our calculations to the  COBE-DMR experiment and test the consistency of the model with the observational results. We also show that an experiment with smaller angular resolution can put bounds to the model parameters.
