Zusammenfassung: | 1. A flexible hose with mutually parallel annular corrugations, coupling parts at his ends and, for holding the latter against changes in axial spacing, longitudinal support means which are rigidly connected in the tensile and/or compressive direction and which are in the form of two flexible cables extending externally of the hose and in parallel therewith on essentially diametrally mutually opposite sides, wherein the relative position between hose and cables is given by spacers distributed at intervals along the length of the hose and inserted into the troughs of the corrugations thereof, the spacers being in the form of annular disks consisting of two like halves with recesses for receiving the cables, and wherein the hose is radially guided and supported by the cables, characterised in that the annular disk halves (2, 3; 8, 9; 11, 12; 16, 25, 30, 35, 36, 39, 40, 53, 54) are held or joined together by closure means without the aid of the cables (4, 5, 15, 29, 33, 34, 43, 44, 55, 56). |
