In order to safeguard a detachable bollard with lock so that there is no possibility of the latter being activated by unauthorised persons and so that it can be activated at a convenient height, a standpipe (1) is arranged rotatably by means of a bearing element (4) on a support body (8) and is mounted on this by means of a bayonet catch (15, 26, 26') a safety lock (24) being provided at the top of the standpipe and a locking bolt (17) being provided at the bottom and connected to the safety lock (24) by means of a pulling member (22). A spacer disk (2) on the standpipe (1) can be connected to the bearing element (4) by securing elements (12), which have predetermined break points (13). <IMAGE> |
