<p>A method of fixing a cord spool support (40) in a longitudinally-elongated head rail (30) or bottom rail of a window covering, so that the support holds an end of a longitudinally-extending cord spool (62) adjacent to a longitudinally-extending opening (39) in the rail. The support is provided with a longitudinally- and vertically-extending groove (46) in a top or bottom surface at a lateral side. In the groove is seated a horizontally-extending base portion (12) of a generally planar, U-shaped metal wire spring (10), having two generally vertically-extending arm portions (14) attached to the base portion and two acutely-angled arm portions (16) which are attached to the vertically-extending arm portions, extend away from the base portion and terminate in ends (18) with sharp edges.</p> |
