摘要： A corrugated tube that can be folded open, for holding cables, comprises: first and second corrugated tube shells, which have a respective plurality of first and second corrugated tube ribs extending peripherally around the respective corrugated tube shell, a joint section, which separates the corrugated tube ribs from each other and pivotably connects the corrugated tube shells to each other, at least one lip section, which is provided on at least one of the corrugated tube shells, and a locking device for locking the two corrugated tube shells to each other when the corrugated tube is brought from a folded-open state into a folded-together state. The locking device includes the corrugated tube ribs, and in the folded-together state, the second corrugated tube ribs extend around the first corrugated tube ribs interlockingly both in a radial direction and in a peripheral direction of the corrugated tube.

摘要： 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.

摘要： A receiving device, in particular a distributor, for receiving a tube for electric cables, comprises a main part with at least one receiving section in which an end portion of the tube can be received. The main part has first and second half-shells, between which the end portion is arranged. The receiving device also comprises multiple spring-elastically deformable engagement sections which protrude radially into the receiving section and which are designed to engage into the tube in a formfitting manner, wherein first and second proportions of the engagement sections is are respectively provided on the half-shells; and an annular section which encircles the receiving section and on which the engagement sections are provided. The annular section is divided into first and second annular segments which are respectively paired with the half-shells. The first annular segment protrudes into the second half-shell in a closed state of the receiving device.

摘要： The invention relates to a corrugated tube made of flexible plastic for encasing wires, having circumferential, successively alternating corrugation crests and corrugation troughs distributed over the axial length thereof, wherein the corrugation crests, seen in cross-section, perpendicular to the longitudinal axis of the corrugated tube, each have a corrugation along the outside circumference thereof which forms alternating radially protruding regions and radially inward-offset regions in the circumferential direction of each corrugation crest. The corrugated tube has wall sections, which extend axially over the length thereof and lie adjacent to each other in the circumferential direction, of which wall sections one forms the radially protruding regions in the corrugation and the other forms the radially inward-offset regions. Said wall sections consist of materials of varying hardness in circumferential alternation.
