An oil boom has a longitudinal hose-shaped floating body (10) of cloth or fabric material, and a skirt (11), also of cloth or fabric material, extending from the floating body and equipped with sinkers (13). The floating body has internal inflatable hoses (16) serving as distension elements. The inflatable hoses are fixed to the floating body and extend in the inflated state substantially in the circumferential direction of the floating body to distend it into hose shape. According to the invention, the inflatable hoses (16) have a sealing layer (20) of elastomeric material and a reinforcing structure (21-25) including a tensile-stress-absorbing inner reinforcing layer (21) and a hose-expansion-limit ing outer reinforcing layer (22, 23; 25). The inner reinforcing layer is formed of substantially parallel reinforcing threads extending in the longitudinal direction of the hose. The outer reinforcing layer includes two sets of reinforcing threads extending helically in opposite directions at an obtuse angle to each other around the hose. Inflatable hoses of this design for distending and stabilising the floating body of an oil boom are also disclosed.
