Abstract: A sealing member having: a sealing material having a cone penetration between 80 and 400 (10.sup.-1 mm) and an ultimate elongation of at least 100%, and an elastomeric retaining member for the sealing material. The retaining member in the form of two connected concentric O-rings.

Abstract: A connector for interconnecting first and second electrical conductors, comprising(a) a first part;(b) a second part; the first and/or second parts forming a housing;(c) a first contact attached to the first part and capable of making contact with the first conductor; and(d) a second contact temporarily attached to the first part and capable of making contact with the second conductor; the second part having means for receiving the second contact when the first and second parts are brought together such that the second contact remains thus received on subsequent separation of the first and second parts.

Abstract: An electrical connector, particularly an insulation-displacement connector of split-beam design, comprising a metal that at constant temperature has an elasticity of at least 0.8%. This allows the connector to be used with conductors over a large diameter range.

Abstract: An electrical connector, which comprises(a) a housing comprising a first part and a second part that can be moved relative to one another,(b) an electrical protection device carried by the first part and being electrically-connectable to a first electrical contact that extends within the housing,(c) a second electrical contact within the housing that has means for connection thereto of an electrical conductor,the first and second electrical contacts being arranged such that connection is made between them on closing the housing and connection between them is broken on opening the housing.
