Protruding from a reservoir in the first of the two plastic parts is an open tube of open-cell foam which is filled with an electrically conductive gel.

This completes an electrical connection between that electrode and an electrode in the first plastic part at the base of the reservoir. The conductive gel may also be carried in a collapsible cup which is biased to force the conductive gel through the fabric to complete the electrical connection.
