The invention relates to construction toys, is light-weight, low in material content, highly manufacturable, and requires less space for storage and transportation. The present building block for a construction set is made of molded paper pulp in the form of a parallelepiped and consists of two separate hollow-bodied elements, the first of which comprises a face having at least four protuberances, and side walls, and the second of which has at least one protuberance; the two block elements are capable of being joined together by fitting the second element between the side walls of the first element, and one of said block elements comprises at least one limiting well.
