ABSTRACT:
The plastic coupling unit includes oppositely directed tubular body portions, each having a circular opening at one end leading into its bore for receiving therein one end of a pole. Each tubular body portion is provided with a resiliently mounted tongue carrying at its free end a latch member that projects through a rectangular side opening into its bore so as to be engageable with a notch in the inserted end of the pole. A longitudinal key is contained in each bore and each inserted pole end has a keyway for receiving a key. In addition, the bores are formed with resilient ribs having sawtooth splines thereon that press against the pole end so that the two pole ends are firmly held by the coupling unit. Any number of coupling units can be employed in order to connect a desired number of poles in an end-to-end relationship.
