  • Patent number: 6123369
    Abstract: A lap joint includes an outer, flexible, cylindrical tube; an inner, solid, cylindrical pipe; and a securing device for compressing the flexible tube around the pipe for securing the flexible tube to the pipe and for providing a substantially leak-free connection between the flexible tube and the pipe. The flexible tube has first and second ends and a first diameter. The flexible tube includes a plurality of captured slots punched through the flexible tube at least at the first end. The plurality of captured slots have a first plurality of metal deformations to prevent circumferential slippage of the flexible tube and are disposed annularly around the flexible tube. Each of the plurality of captured slots are inboard of the first end and do not extend to the first end. The securing device is arranged and configured to completely cover the plurality of captured slots. The flexible tube also includes a plurality of relief slots punched through the flexible tube at least at the first end.
