ABSTRACT:
The invention relates to a coaxial two-component cartridge, with an outer tube and a separate inner tube, both of which tape at one respective end into a respective neck, wherein the inner side of the neck of the outer tube and the outer side of the neck of the inner tube are each provided with locking elements that can be moved into engagement with each other, for a coaxial introduction of the inner tube into the outer tube, such that they fix the inner tube relative to the outer tube coaxially and in a predetermined axial position. The coaxial two-component cartridge distinguishes itself in that the locking elements of the neck of the outer tube are formed by a plurality in the axial direction of successive channels, and the locking elements of the neck of the inner tube are formed by a plurality in the axial direction of successive ribs integral with the neck, and the outer diameter of the neck of the inner tube including the ribs is at least as large as the clearance diameter of the channels.
