An internal device for use in an underwater cable may comprise a body
having an outer periphery, body being mountable inside the cable with the
cable surrounding the outer periphery of the body. The body may include a
cutaway portion, a slot, or a dovetail joint. An underwater cable
arrangement may comprise an underwater cable and an internal device
disposed in the cable with the cable surrounding the device. The
underwater cable may include a stress member connected to the internal
device by an interference fit or the internal device may include a slot
for receiving the stress member. A method of connecting a stress member of
an under water cable to an internal device includes forming an
interference fit between a region of increased diameter of the stress
member and the internal device.
