Flexible convoluted tubing is made of an elastomeric material in desired lengths in which one end has convolutions with a configuration different from the convolutions at the other end. This enables the ends of each length to be interlocked in order to form a continuous closed hose. Alternatively separate lengths of tubing can be joined by interlocking one end of each length of tubing to the dissimilar end of another length of tubing.

In a continuous closed loop hose formed of interlocked ends of a flexible convoluted elastomeric tubing having a cylindrical wall with convolutions integrally formed with said wall; the improvement wherein said convolutions are formed throughout the length thereof and are axially spaced, annular, and circumferentially continuous, and comprise a first set of convolutions identical to each other at one end of said tubing, and a second set of convolutions identical to each other at the other end of said tubing, the convolutions of said second set having a configuration which is different from the configuration of the convolutions of said first set, at least one convolution of each of said first and second sets interengaging each other to form said interlocked ends, whereby said interengaged convolutions are the only means forming said interlocked ends.
