A procedure is proposed for finding local symmetries for the models with a given Lagrange function. The objects obtained by this procedure (in particular, the first- and second-class constraints) are described in terms of the invariant language of symplectic geometry. The one-to-one correspondence between the Lagrangian and Hamiltonian local coordinates is demonstrated.
