A cord tightening device (10) for tightening cords (C) on anoraks, shopping bags and other bags includes a hollow body (11) and a slider (12) movably disposed in the body (11) and slidable along a guide groove (20) defined in a face plate (13) of the body (11). The slider (12) has an annular retainer (22) for pressing cord portions against side walls (15, 16) of the body (11), and a resilient knob (23) cantilevered to the retainer (22) and normally projecting through the guide groove (20) above the face plate (13). The cantilevered knob (23) is resiliently flexible toward the back plate (14) to such an extent that the knob (23) is substantially fully received in an aperture (24) in the retainer (22). With this resilient knob (23), the slider (12) can smoothly be inserted in and removed from the body (11) without damaging the body (11). |
