A sleeve socket (1) or similar, and a clamping device located in its head part, provide anchorage for a tubular post in the ground (3). The clamping device consists of an eccentric disc (5) or eccentric piece, or similar, which can be twisted in relation to the post, which may be guided so as to fit in the socket. The eccentric unit can have two holes, in the axial direction of the posts, to accommodate lugs, or similar, on a key. The socket head part may have a housing to fit the eccentric unit, with outer walling running in the socket's axial line, or the clamping device can consist of two separated eccentric sleeves. |
