Date May 26, 1994.An object of the present invention is to provide a hose of low cost, which can be installed very easily, which remains reliable over a long period of time, and in which damage to the inner construction can be easily discovered. An auxiliary pressure cord layer 7 is capable of being deformed by the pressure of a fluid in a chamber 9. A float 10 attached to a hose 1 with a mooring line is also attached to a hose body 2 through a connecting member, and when an amount of deformation of the auxiliary pressure cord layer 7 has reached a predetermined value, the connecting member is fractured and the float 10 is separated from the hose 1.
