A segmented sealing assembly includes a first sealing segment having a first resilient sealing element with a first primary sealing surface and a tongue having a secondary sealing surface, and a second sealing segment having a second resilient sealing element with a second primary sealing surface and a groove having another secondary sealing surface. The first and second sealing segments are movable into a contact engagement to form the sealing assembly. When the first and second sealing segments are moved into the contact engagement, the first and second primary sealing surfaces form a primary seal, and the tongue and the groove form a secondary seal.
