Abstract
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.
