ABSTRACT:
A coupling structure includes two couplings joined back-to-back as a unit by means of a bolt, each coupling consisting of a box-like base, a pair of non-skid blocks disposed within the base, a cover pivotally connected to the base, a press plate and a couple of adjusting screw bolts. The base is provided with notches in its two longitudinal walls for supporting a tube. The non-skid blocks are respectively provided with upper non-skid surfaces for urging against a lower portion of the tube. After the tube is mounted within the base, the cover is locked in place by means of the screw bolts which join the press plate to the cover and pass through corresponding holes in the base and the non-skid blocks to secure the tube.
