Improvements in limit marking units of the kind comprising at least two holes (1h or 2f) for connecting and/or anchoring members (5) serving for interconnecting units (1 and/or 2) and/or for anchoring a unit (1 or 2) or units (1 and/or 2) to a base (6). For the purpose, in a simple way to provide a simple and low-cost limit marking unit having very good strength characteristics, the improvements according to the present invention are characterised by at least one reinforcement member (7) which extends from one hole (1h or 2f) for a connecting and/or anchoring member to another and surrounds these holes (1h or 2f). |
