ABSTRACT:
A slide-n-snap in support fitting 14 for motion transmitting remote control assembly of the type for transmitting motion by a flexible motion transmitting core element 12. The fitting 14 presents a pair of spaced inner 24 and outer 26 flanges for receiving therebetween the edge of a slot 18 in the support structure 16 and a pair of locking arms 22 extend in a cantilevered fashion a direction transverse to the guideways 20 defined by the flanges 24 and 26 for flexing about an axis parallel to the guideways 20 and remaining inflexible in the direction parallel to the guideways 20 for extending over the support structure 16 adjacent the slot 18 therein while flexing about the axis parallel to the guideways 20 during insertion of the fitting 14 into the slot 18 and snapping back into mechanical interlocking engagement with the end of a ramp 32 projecting from the support structure 16 in the locked position so that forces urging the fitting 14 out of the locked position in the slot 18 will react with the arms 22 in the inflexible direction, thereby providing relatively low force to insert the fitting 14 into the slot 18 while providing a relatively high retention force to prevent the fitting 14 from being removed from the slot 18.
