In sub-Riemannian geometry the coefficients of the Jacobi equation define curvature-like invariants. We show that these coefficients can be interpreted as the curvature of a canonical Ehresmann connection associated to the metric, first introduced in Zelenko-Li. We show why this connection is naturally nonlinear, and we discuss some of its properties.
