More Information
Summary:A corrugated tube assembly comprises an inner and an outer corrugated tube made of plastic with circumferential corrugations and with a respective longitudinal slot. A longitudinal strip on the inner corrugated tube with corrugations with the same shape and distribution as the corrugations on the outer corrugated tube protrudes into the longitudinal slot of the outer corrugated tube, the outer diameter of the respective corrugations corresponding to one another. The terminal cross-sections of all the corrugations on both corrugated tubes are closed. The two longitudinal sides of the longitudinal strip are connected to the rest of the inner corrugated tube via a respective V-shaped depression. When the two corrugated tubes are plugged together such that the corrugations of the two corrugated tubes are in engagement, each lateral edge of the longitudinal slot of the outer corrugated tube protrudes into a V-shaped depression of the inner corrugated tube.
