Abstract: The invention concerns a ground anchor or rock anchor, in particular permanent anchor, having an anchor tension member composed of one or more individual elements (3, 31), such as steel bars, steel wires, or steel wire strands, for example. While the anchor tension member is intended to be introduced into a drilled hole (2) and anchored there, the anchoring of the anchor tension member at the exposed end of the drilled hole (2) is achieved with the aid of a specific anchor head design (7). To this end, the anchor head design (7) comprises a support element (8, 26, 26') to bear directly or indirectly against the underlying rock or substratum (10), and further comprises anchoring means (14) for tensioning the individual elements (3), which can be brought into a frictional connection with the individual elements (3) while bearing against the support element (8, 26, 26'). In addition, a cap (17), which extends around the anchoring means (14) and the ends of the individual elements (3), protects the exposed end of the anchor head (7). For secure attachment of the cap (17) to the rest of the anchor head (7), provision is made according to the invention that, between the support element (8, 26, 26') and anchoring means (14) is arranged a connecting element (12, 25, 38), which has first closure means at its circumferential side, and that the cap (17) has second closure means of complementary shape on its circumferential side, wherein the first and second closure means work together to produce a frictional connection between the cap (17) and connecting element (13, 25).
