The technicial manual calls this a clamp, hose hi torque
A clamp in which the body (band or wire) completely encircles an item and distributes a relatively even amount of pressure throughout the entire 360 degrees (6.282 radians) of the periphery of the item to be compressed. Its compression quality is dependent upon an integral screw mechanism, (screw, bolt spring compression and the like mechanical fasteners), or it may be applied by a device not integral with the clamp itself. It is specifically designed to prevent leakage between a hose and its attaching connection(s) when the body of the clamp is round or circular. For square, rectangular, or irregularly shaped items, see clamp, hose, special-shaped. Excludes clamp, electrical; clamp, loop; clamp, fire hose, shutoff; ferrule (as modified); and hand screw.
