Abstract:
A lap joint comprising:(a) an outer, flexible, cylindrical tube having first and second ends and a first diameter, the flexible tube including:(i) a plurality of captured slots punched through the flexible tube at least at the first end;(A) the plurality of captured slots having a first plurality of metal deformations to prevent circumferential slippage of the flexible tube;(B) the plurality of captured slots being disposed annularly around the flexible tube;(C) each of the plurality of captured slots being inboard of the first end and not extending to the first end;(ii) a plurality of relief slots punched through the flexible tube at least at the first end;(A) the plurality of relief slots having a second plurality of metal deformations to prevent circumferential slippage of the flexible tube;(B) the plurality of relief slots being disposed annularly around the flexible tube;(C) each of the plurality of relief slots extending to the first end and extending a first distance inboard of the captured slots;(D) each of the plurality of relief slots being offset a second distance from the relief slots;(b) an inner, solid, cylindrical pipe having first and second ends;(i) the first end of the pipe having a second diameter less than the first diameter of the flexible tube;(ii) the first end of the pipe being arranged and configured to telescopically slide within the first end of the flexible tube;(c) 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 securing device arranged and configured to completely cover the plurality of captured slots; and(d) a compression indicator for indicating the relative compression of the flexible tube.
