<p>A connector (20) for pipe snake rods has a first rod element (21), a second rod element (22) and a collar (23). The rod elements (21,22) are attached respectively to the rods (11,12), and each has an outer thread (213,223) and an abutting protrusion (212,222). The collar (23) has an inner thread (231) screwed onto the outer threads (213,223) on the rod elements (21,22) to connect the rod elements (21,22) together. The abutting protrusions (212,222) are mated to each other when the rod elements (21,22) are connected together. Accordingly, the connector (20) can keep the rods (11,12) from separating from each other when the pipe snake is operating and make the pipe snake convenient and versatile in use. <IMAGE></p> |
