Seals particularly for cable splice closures having two diametrically opposed sealing members. The sealing members are of soft material with a maximum Shore hardness of 15 and preferably a Shore hardness of 10. A sealing rib of each sealing member extends into a cavity to be occupied by the cable with the sealing members assembled together. Each sealing rib bridges axially between a seal base and a rib stiffening element which is spaced axially of the base and inwardly of the radially outer limits of the base. When assembled into a housing with the base of the seal supported by the housing, the rib stiffening element is spaced from the housing. The rib is deflected radially outwards by engagement with a cable and causes outward resilient deflection of the rib stiffening element which provides resilient support for the rib while permitting it to deflect over a wide range of diameters.

Seals

Aerial splice closures with a closure casing of two casing portions and an elastomeric seal at each end of the closure. Each seal has two seal halves with each seal half having an outwardly extending resilient lug which passes through an aperture formed in its casing portion to mount the seal half in the casing portion. Preferably, each lug has a lateral flange which engages the outside surface of the casing portion.
