ABSTRACT:
A pair of concentric hoses of flexible elastomeric material are spaced radially apart to define an annular space around the inner hose. Both hoses are secured at each of their ends to a common connector ring for securing successive lengths of the double hose together. Passages through the connector rings provide communication between the annular spaces.
