        ITable originTable = featureWorkspace.OpenTable(nameOfOriginTable);
        ITable destTable = featureWorkspace.OpenTable(nameOfDestinationTable);

Here is a fragment of code showing the use of this property:

Dim pRelationshipClass As IRelationshipClass
Set pRelationshipClass = pFeatureWorkspace.OpenRelationshipClass("relclass")

Dim pOriginTable As ITable
Set pOriginTable = pFeatureWorkspace.OpenTable("origintable")

Dim pDestinationTable As ITable
Set pDestinationTable = pFeatureWorkspace.OpenTable("destinationtable")

Dim pOriginFeature As IFeature
Set pOriginFeature = pOriginTable.GetRow(2)

Dim  pDestinationFeature As IFeature
Set  pDestinationFeature = pDestinationTable.GetRow(2)

pRelationshipClass.DeleteRelationship(pOriginFeature, pDestinationFeature)
