They were rather large. The pipes/tubes were yellow, the connectors were red, green, and blue and came in shapes of tubes, elbows, and T's. There were also orange and yellow panels to make walls and floors. All these were held together by multi-colored C clips. They were popular in the late 80s. I can't find any information or pictures anywhere, and I would like to reacquire these toys.
Thanks!
