An end of a composite cylinder (40) is formed about a multipiece end assembly (42) having a contour which prevents the withdrawal of the end assembly from the cylinder. The pieces (42a, 42b) of the end assembly are relatively forced apart and a spacer (46) is positioned between the parts to maintain the pieces in intimate contact with the inner surface of the cylinder thus preloading the end prior to application of an axial load or removing any residual gap from the manufacturing process. The cylinder may have end assemblies at both ends and to which may be coupled external connectors such as flange members, for construction of a marine riser.
