The device is characterized in that said centre (1) comprises preferably equal grooves (3) located in said plane, that each groove (3) opens in two places (5, 6) at the periphery (4) of said centre and extends in an arc (7), which preferably is a part of a circular arc (7), between said places (5, 6), and in each groove (3) an attachment ring (8) for a chain (11) is located and partially projects outside the periphery (4) of said centre (1), and the grooves (3) at least partially are covered by a cover (9) or the like. </p> |
