An assembly for covering at least a portion of a cable, such as an electric cable, comprises an elastomeric tube and a hybrid support core structure. The hybrid core structure includes a central core structure formed from a spirally wound separable ribbon that supports a central portion of the elastomeric tube in a radially expanded state, and first and second solid end core structures that support first and second end portions of the elastomeric tube in a radially expanded state. Each solid end core structure has a film disposed on at least an inner surface thereof having a coefficient of friction less than or equal to 0.05.
