Let L(m) be the bundle of all linear frames over a smooth manifold M, u an arbitrarily given point of L(M), and ▽:x(M) ×x(M) →x(M) a linear connection on M. Then the following result is well known: the horizontal subspace at the point u may be written in terms of local coordinates of u∈L(M) and Christoffel`s symbols defined by ▽. This result is very fundamental on the study of the theory of connections. In this paper we show that local expression of the horizontal subspace at the point u does not depend on the choice of a local coordinate systerm around the point u∈(M), which is rarely seen.
