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. Closure of the joint simply comprises the reverse of this operation.

Sealed jointing apparatus for use in the connection of conduit sections comprising an annular casing having open ends; spaced end closures at the ends of the casing, and defining with the casing a connection zone into which conduit sections pass for jointing; and releasable securing means for releasably securing at least one of the end closures to the casing; said releasable securing means comprising an end cap having an aperture and including two radially spaced coupling threads, one of which coupling threads threadingly engages an external thread on the casing while the other coupling thread engages an internal thread on said at least one end closure whereby the casing is releasably coupled to said at least one end closure.
