Abstract

An apparatus (1) for sealing the end of an elongate cable (73) such as a heating cable comprises 1) a housing (3) with a first open end (5) and a second open end (7) and a strain relief element (27) positioned within the housing, 2) a flexible container (43) which can be positioned over the cable end (75) and (i) is of generaly tubular shape; (ii) has an interior surface (53) and an exterior surface (55); (iii) has a first open end (47) and a second closed end (49); and (iv) contains a sealant (77); and 3) a cap (61) which can be mated with the housing at the second open end, and cover the flexible container. The apparatus has excellent moisture-resistant properties even after repeated exposure to high temperatures, is reenterable, and can be readily mounted on a substrate such as a pipe. Also disclosed is an apparatus (80) for sealing a core (103) of an elongate heating cable (101). The apparatus comprises a flexible container (81) in which a first portion (83) is attached to a second portion (89) which comprises first and second leg portions (91, 93) suitable for insertion of first and second elongate electrodes (105, 107) of the heating cable.
