ABSTRACT:
A motion-transmitting remote control assembly of the type including a flexible motion-transmitting core element movably supported in a conduit (28) supported by a fitting (12). A helical groove (24 ) is formed in a bore (14) in the fitting (12) and a raised helical ridge (30) extends radially from the conduit (28) and fills the helical groove (24) to provide retention of the conduit (28) within the bore (14) of the fitting (12). An apparatus (10) and method for attaching the fitting (12) to the conduit (28) wherein the fitting (12) is rotatably supported by a mandrel (82) as the conduit (28) is clamped (42) and forced into the bore whereby frictional engagement with the bore (14) of specific configuration causes the material of the conduit (28) to soften and move radially outwardly (30) to fill the helical groove (24).
