ABSTRACT OF THE DISCLOSURE A flexible corrugated tube made of spirally coiled thin metal strip is disclosed. The tube has overlapping convolutions which use less material than previous types of tubes and is also highly flexible and resilient in the axial direction. The tube comprises a succession of axially displaced convolutions of spi- rally coiled thin metal strip having longitudinally extending corrugations, the corrugations being of wave form having alter- nate arcuate axially spaced crests and troughs, the borders of successive tube convolutions overlapping each other with at least one corrugation in the overlying border portion of one convolu- tion fitting into one corrugation of the underlying border por- tion of an adjoining convolution, a plurality of detents are pro- vided in the interfitting corrugations, the detents are circum- ferentially spaced apart and positioned about the interfitting corrugations, portions of the interfitting corrugations having the wave form extending between the detents, and each detent forms a generally S-shaped crimp in the interfitting corrugations and locks together the interfitting corrugations in the border portions of the overlapping convolutions, the corrugations lying one within the other and containing detents having sides in the form of lateral walls outside the detents, running approximately perpendicularly to the axis of the tube, whereas the corrugations therebetween, having no detents, have sides of V-shaped cross- section, with sides extending obliquely in relation to the axis of the tube.
