Abstract
A support coil for radially supporting an elastically expanded tube material includes an extruded profile body consisting of a plurality of windings wound about a longitudinal axis of the support coil. Each of the windings has opposing end faces. A ratchet arrangement joins the end faces of the adjacent windings with respect to the longitudinal axis of the support coil. A tongue and groove arrangement joins the end faces of the adjacent windings with respect to a radial direction of the support coil. The tongue and groove arrangement is spatially separated from the ratchet arrangement.

A support coil for radially supporting an elastically expanded tube material, comprising:
- an extruded profile body consisting of a plurality of windings wound about a longitudinal axis of the support coil, each of the windings having opposing end faces;
- a ratchet arrangement having a ratchet element joining the end faces of the adjacent windings with respect to the longitudinal axis of the support coil;
- a tongue and groove arrangement joining the end faces of the adjacent windings with respect to a radial direction of the support coil, the tongue and groove arrangement being spatially separated from the ratchet arrangement;
- wherein the tongue and groove arrangement is formed between a radial external surface and a radial internal surface of the support coil with the tongue projecting from one end face and the groove providing an opening located in an opposite end face, spaced apart from the external and internal surfaces.
