Hose with releasable float for leak detection

A hose (1) includes a main pressure cord layer (5) for holding a fluid, and an auxiliary pressure cord layer (7) formed so as to sheathe the main pressure cord layer (5) and to form a buffering space (9) for retaining the fluid leaking through the main pressure cord layer (5) between the main pressure cord layer (5) and the auxiliary pressure cord layer (7). The auxiliary cord layer (7) includes first and second cord plies in an asymmetrical structural relation capable of being twisted by the pressure of the fluid leaking through the main pressure cord layer (5). Thus, even if its main pressure cord layer and its rubber tube are damaged leakage of the fluid can be prevented.
