In the present invention there is provided, a pipe connector for use in tendons, risers or other pipe connections. The pipe connector comprises a tubular pin member and a tubular box member. The tubular pin member has a frusto-conical outer peripheral surface, an inner axial end and outer axial end. The tubular box member is telescopically engageable with the pin member and has a frusto-conical inner peripheral surface that further has an inner axial end and an outer axial end. The frusto-conical inner peripheral surface of the tubular box member corresponds to the frusto-conical surface of the pin member and overlies the frusto-conical surface of the pin member when the members are engaged. There is provided annular projection and groove means in the frusto-conical surfaces of the pin member and the box member that interengageable to axially lock the pin member and the box member together. A system for assembling tension-leg pipes using the claimed connector is also provided. A system for assembling machined pipe pieces is provided as well.
