Abstract
We prove the existence and uniqueness of a linear connection on a semi{ Riemannian distribution which satisfles similar conditions as the Levi{Civita connection on a semi{Riemannian manifold. When the ambient manifold is semi{Riemannian too, we study its geometrical properties related to two orthogonal complementary distributions. Finally, we construct a non{holonomic manifold on which a bundle{like metric exists. Mathematics Subject Classiflcation 2000: 53C07, 53C12.
