Connectors for joining a ball element having multiple facets, each facet defining a joint opening, to a toy brick include at least two projections in spaced relationship with each other mounted on a base. The projections are in releasable frictional engagement with the joint opening. A female connector frictionally engages with a male face of a brick. The female connector includes a set of four prongs, each having gripping sides, projecting symmetrically outward from the base. Adjacent gripping sides of adjacent prongs frictionally grip cylindrical protrusions of the male face. A male connector may join with a brick having a female face with symmetrically arranged gripping surfaces. The male connector frictionally engages a female side of a brick. The male connector includes a set of four prongs, projecting symmetrically downward from the base. Each of the prongs has exterior gripping surfaces for frictionally engaging gripping surfaces of the female face.
