ABSTRACT:
A quick-coupling post for trampoline safety fence is formed from a plurality of sequentially connectable hollow sections and an elastic connecting element mounted in each section. Each of the hollow sections has an upper portion adapted to fitly extend into a lower portion of another section to align two through holes separately provided at the upper and the lower portion of the two hollow sections, respectively. The elastic connecting element is in the form of a letter V to include two normally outward stretched arms that naturally elastically press against two opposite inner surfaces of the hollow section. One of the two arms is provided at a free end with a short shaft tube that elastically extends through the two aligned through holes on two coupled hollow sections to hold the two coupled sections in place relative to each other.
