A flexible protective sleeve 10 comprises a generally tubular wall 12 substantially enclosing a space 14 for containing an elongated member such as a bundle of wires or a pipe. The wall comprises a layer 22 formed from flexible sheet material having a density which is no more than 30% of the theoretical density of the material, the material also being resilient. The sleeve is manufactured by a method which comprises winding at least one strip 20 of said flexible sheet material of substantially constant thickness and width along the length of the strip into the shape of a helix of substantially constant diameter, the method also comprising fixing said strip in its helical form. Each strip winding 20 may abut the previous strip winding 20 (as shown) or may overlap (eg. figure 3). |
