Said housing represents a multistart helical surface arranged along its edges with helical grooves inside and outside at 5 to 45 degrees to jacket lengthwise axis and shaped to birecurvate recesses. Centers of curvature of said recesses are located inside and outside jacket cross-section. Jacket is composed of equal-width one or more tapes coiled in helical turns interconnected by lengthwise edges. Said tapes are bent in zigzag manner along flexure lines arranged at angle to lengthwise edges. Said tapes form, along outer and inner surfaces, wavy helical surfaces shaped to curved recesses directed to one side at 5 to 45 degrees to jacket lengthwise axis. Said recesses may differ in both shape and size. Distance between flexure lines equal the sum of lengths of perimeters of geometrical figures of inner and outer surface recesses.
