A new structure for children's games. It comprises corner components (1) and side components (2) in which the means for the assembly thereof are integrated, formed by oblique extensions (5) of material having an alternate slope relative to the components (1) with the free edges thereof curved inwards in opposite directions to form longitudinal guideways in said components (1) for sliding and retaining rounded section edges (6) which extend along the vertical sides of the components (2), with which they are connected by thinner portions (20). The structure is applicable to the assembly and dismantling of constructions for children's games, without the need of auxiliary tooling or independent connecting means for the components integrating the structure. <IMAGE>
