A shielded cable passes through a kickpipe in a structural plate member, such as the deck of a ship. The kickpipe has a necked-down portion designed to receive the cable at a point where the cable shielding has been exposed. Axially compressible radially expandable iris, or toroidal, springs are engaged by an adapter nut threadably received inside the kickpipe to create a low impedance ground connection from the cable shielding to the deck. The adapter nut has a cavity for receiving a packing material and a gland nut is received in the adapter cavity to seal the ground connection from the environment.
