ABSTRACT:
A coupling is provided between a flex hose and a rigid pipe by a lap joint with an end of the rigid pipe inserted into an end of the flex hose to form an overlap region. The flex hose has at least one slot through its wall extending axially of the flex hose and spanning the helical strip in a convolution which is in the overlap region. The slot is spaced inwardly from the end of the flex hose. A clamp disposed around the flex hose covers the slot and clamps the flex hose and pipe together collapsing the overlap region of the flex hose by circumferential slippage of adjacent convolutions of the helical strip to cause close engagement of the flex hose with the pipe and with the band clamp.
