Abstract

An improved frictional interconnecting toy block arrangement having a body means with walls defining a body cavity. The interconnection of toy blocks with each other is achieved by a female coupler means extending through the cavity of the body means of the toy block and having an aperture adapted to receive a male coupler means. Male coupler means which extends outwardly from a wall of the toy block is insertable into the aperture of the female coupler means for frictional retention therein. The male coupler means are generally fabricated as part of the body means of the block. The body means of the block is fabricated of two separate body members coupled together along a median plane. Coupling means are provided on the two body members to retain the two body members together. Provision of the body means comprised of the two separate body members allows each body member to be fabricated to provide a different appearance such as, for example, different color, different surface texture, or the like, thereby enhancing the play value of the toy block arrangement.
