Abstract: A one-piece molded end plug for insertion in the end portion of an elongated window shade rod with the end plug being movable relative to the end of the rod between a number of preselected positions so as to adjust the effective length of the rod. In each of the positions, a portion of the plug positively abuts the end of the rod to prevent unintended further insertion of the plug into the rod. The portions of the plug abutting the end of the rod in the various positions are stops, all but the outermost of which are selectively movable or removable to allow the plug to be inserted further into the end portion of the rod. The two innermost stops are flexible protrusions which are molded integrally with the plug and which are movable between retracted positions in which they may telescope into the rod and extended or normal positions in which they abut the end of the rod. The next to the outermost stop is formed by a number of angularly spaced tabs which may be sliced away and removed from the plug.
