ABSTRACT:
The plant/vine support disclosed utilized a channel shaped post having a U-shaped central portion and a pair of laterally projecting flanges with locking lug pairs integrally formed on the flanges and a locking lug and shoulders in the U-shape of the post. The ring is provided with a complementary shaped locking structure which is coplaner with the ring support per se and adapted to interengagingly locking maneuver as well as a simple unlocking and disassembling maneuver. The rings are simple, stack flat and are far less susceptible of hooking with one another and thereby entangling themselves during storage.
