ABSTRACT:
An improved cable fitting which consists of a material which is shrinkable under the influence of heat and which has at least one sealing area provided with a sealing device including adhesive agents which are also influenced by heat characterized by the sealing device being a permanent plastic sealing member which is disposed between two adhesive layers. The sealing area of the fitting may be a closure area which has a separation plane defined by a pair of flanges and/or may be a socket-like area or opening in which a cable is inserted through. In either instance, the improved sealing device ensures the required mechanical stability through the use of the adhesive layer and the permanent plastic sealing member or insert ensures sealing against humidity.
