ABSTRACT:
A wire gripping clamp has a rubber inner tube wedged to the ends of a rigid outer tube by a set of rings, one ring at each tube end. The space between the tubes is sealed by the rings and forms a chamber, which when pressurized, compresses the inner tube wedging the rings against it. The compressed inner tube grasps an insulated wire passing therethrough without damage to the wire. The rings serve as a clamp in response to tension on the inner tube and as a guide for the wire when the wire is displaced through the device for precluding damage to the inner tube and to the wire during that relative displacement.
