For a manifold M endowed with a Legendrean (or Lagrangean) contact structure E⊕F⊂TM, we give an elementary construction of an invariant partial connection on the quotient bundle TM/F. This permits us to develop a naïve version of relative tractor calculus and to construct a second order invariant differential operator, which turns out to be the first relative BGG operator induced by the partial connection.
