Abstract: A cable seal insert for sealing a cable entry in a closure, including:(a) at least two plates, each of which, at least in use, has extending therethrough at least one aperture for a cable; and(b) sealing material located between the plates;wherein a peripheral surface of the seal insert which is substantially parallel to the or each cable aperture is substantially planar, and at least one of the plates is formed from non-elastomeric material.

Abstract: A seal for sealing between a cable and a casing enclosing part of the cable includes a wall member having a plurality of substantially concentric removable portions which may selectively removed to provide a cable aperture of required diameter through the wall member. The seal also includes sealing material retained by the wall member, which seals, in use, around a cable extending through the cable aperture in the wall member. When a removable portion of the wall member is removed, a corresponding portion of the sealing material is also removed, thereby providing a cable aperture of the required diameter through the sealing material.

Abstract: A retention strip for winding around an elongate object is disclosed. When the strip is wound in use it can decrease in length when compressed around the object, thereby contracting around the object. The strip preferably includes one or more, preferably a plurality of, collapsible portions, and the strip can decrease in length due to the collapsing of one or more of the collapsible portions.

Abstract: A cable splice closure is disclosed, which includes a casing which, in use, is closed around a cable splice; and at least one cable gripper comprising a strip which, in use, is wound around at least one cable extending into the casing. Closing the casing, in use, automatically causes the or each strip to tighten around the or each cable around which it is wound, thereby gripping the cable. The cable gripper strip may have the ability to decrease in length when wound and compressed around a cable, thereby allowing it to contract, and therefore tighten, around the cable.

Abstract: A device for forming a seal around an elongate object having: (a) a sealing plate having a hole through which the object can pass, and containing a chamber in communication with the hole; (b) a pressure plate positioned within and movable relative to the chamber; and (c) a sealing material positioned within the chamber such that when the elongate object passes, in use, through the hole in the sealing plate, the sealing material is positioned between the pressure plate and the elongate object, wherein the pressure plate can be moved, in use, towards the object in a direction transversely of the object, to urge the sealing material into sealing contact with the object.
