Abstract
A connector for a composite pipe includes a male conical member to be inserted between inner and outer layers of the pipe. The outer layers have oppositely wound composite strips which are overlapped along the conical surface. The ends of the strips are braided and a cup located over the conical surface. A filler is injected between the cup and conical member to fill the voids formed between the overlapping strips.
