Abstract: A set of bricks has plugging connections which, on the top side, have male elements and at their lower sides have female pockets to take up the male elements on another such brick. Two bricks may be put together by pushing the male elements of the one brick into the female pockets of the other brick. The material of the bricks is soft synthetic resin, such as high-pressure polyethylene (PE-soft) which has good gripping properties, keeps its form, is not damaged by abrasion and keeps to the conditions of laws in connection with the use of synthetic resins with foodstuffs. The female pockets which are placed coaxially with respect to the male elements are formed by sleeve-like wall parts which, at the outer sides of the brick, have rounded off brick corners and in the inner part of the bricks are responsible for forming bracing walls.
