Abstract
An insulator comprising a plurality of fins (1) or one-piece groups of fins made of elastomer and having sleeves (2) disposed end-to-end. The fins surround a central member (3) and are vulcanized. The fins form a water-tight tube whose cohesion is ensured at least by vulcanizing intermediate elastomer portions (5) which are inserted raw between vulcanized fins or one-piece groups of fins and adhere to the facing surfaces of the said sleeves by virtue of their subsequent vulcanization.
