Abstract: A device for forming a seal around an elongate member, such as a wire, is provided. A device includes a first housing part and a second housing part movably connected to the first part. Sealing material such as a gel is positioned in the first housing part and provides a surface onto which the elongate member may be placed. A first member is positioned in the second housing part so as to displace the elongate member substantially laterally into the sealing material on movement of the second housing part relative to the first housing part. A device for applying a force to the sealing material on relative movement of the housing parts is also provided.

Abstract: A device for environmental protection of an electrical component on a mount, e.g. a circuit board, includes: a first housing part; a second housing part which together with the first housing part provides a substantially closed housing; a mount (e.g. a circuit board) for an electrical component that may be movably secured with respect to the first housing part; and a sealing material positioned between the mount and a surface of the first housing part; such that the mount can be moved with respect to the first housing part to put the sealing material under compression. The device can also include a maintenance termination unit for a telecommunications network.
