ABSTRACT:
A coil holder for one or several coils arranged one after the other has a main pipe having an outer periphery provided with recesses forming abutment surfaces which are wedge-shaped in an axial direction of the main pipe, a plurality of clamping elements arranged in groups axially arranged one behind the other and each distributed on a circumferential line of the main pipe so as to partially engage in the recesses in the outer periphery of the main pipe, a cylindrical displacing element surrounds the main pipe, a device for displacing the displacing element, the displacing element being formed as a displacing pipe which surrounds at least two of the groups of the clamping elements, the recesses of the main pipe being limited in a circumferential direction and having a width substantially equal to a width of the clamping elements and the displacing element includes openings through which the clamping elements are adapted to extend to hold the coil or several coils on the main pipe.
