The plastics element has male coupling members (9) which project from the outer frame (1) as elongated bars parallel to the plane of the element. Each female coupling element (13) lying within the outer frame has two spring-elastic catches (14,15) which grip behind the bar (9). The elongated bar has a stop (10) for the two catches. The stop is made as a plate which protrudes over the face side of the bar. |
