Abstract: Sealed jointing apparatus is for use in the connection of conduit sections, at a connection zone, especially but not exclusively telecommunication cable sections. The apparatus comprises end closure means (3) bounding the connection zone and surrounding the respective conduit sections (2). Primary seal means (9) is for location between the end closure means (3) and the conduit sections (2). Casing means (17) surrounds the end portions of the conduit sections at said connection zone, and releasable securing means (19) for sealingly securing the casing means and the closure means (3). The conductor splices in joined telecommunication cable sections can be contained in a hermetically sealed zone bounded by the end closure means (3) and the casing (17) and access can be had to the cable splices simply by releasing the releasable securing means (19) and pushing the casing (17) aside. The end closure means (3) remain in position and the primary seal means (9) are untouched.
