Title: Collar for taking hold of fixation piece of window shade rod

Abstract: A tubular collar is used to take hold of a fixation piece at one longitudinal end of a window shade rod. The collar is provided in an outer wall with a plurality of axial grooves extending through both longitudinal ends of the collar. The collar is provided in an interior with an inner tube extending along the longitudinal direction of the collar. The inner tube is provided with a groove segment and a grooveless segment. The fixation piece is set firmly in place in such a way that the grooved segment of the inner tube is caused to expand by a projection of the fixation piece so as to force the collar to press against the inner wall of a hole of the longitudinal ends of the window shade rod, and that the projection of the fixation piece is intimately embraced by the grooveless segment of the inner tube.
