ABSTRACT:
A plurality of internal couplers (A, B, C. D) are integrally connected end to end in a single tubing construction of indeterminant length. Between each coupler is an annular, frangible region (14, 24) of thin plastic. In the field, the individual couplers are readily broken manually from the tubing construction. Each coupler includes a plurality of cleats (40) which are partially surrounded by a region (50) of relatively thin plastic material. The couplers are manufactured by continuously blow molding a sleeve of softened plastic into the tubing construction of indeterminent length.
