On a manifold with an almost contact metric structure we introduce the notions of interior connection, $N$-extended connection and $N$-connection. It is shown that the Tanaka–Webster and Schouten–van Kampen connections are a special cases of $N$-connection. We define new classes of $N$-connections is the Wagner connection and canonical metric $N$-connection. We also define $N$-extended symplectic connection. It is proved that the $N$-extended symplectic connection exists on any manifold with a contact metric structure.
