Abstract: A coupling assembly for coupling a first rod member with a second rod member, where the assembly includes a male connecting end of the first rod member being adapted for being received into a female connecting end of the second rod member, and a locking mechanism for preventing the first and second rod members from being uncoupled. The locking mechanism includes a stop positioned in between the male connecting end and a locking member such that during use the locking member engages at least a part of the female connecting end and the stop thereby preventing the male connecting end from being withdrawn from the female connecting end.
