ABSTRACT:
A motion-transmitting remote control assembly (10) comprises a flexible conduit (14) with a flexible core element (12) passing therethrough. The flexible conduit (14) has a male coupler (22) attached to one end of the flexible conduit (14). The male coupler (22) comprises a leading chamfered surface (24) and a relief (26) for being locked into a first type of female housing (28) via a spring biased locking ring (32). The male coupler (22) also includes a truncated convex surface (29) which, along with the relief (26), allows the male coupler (22) to be locked into a second type of female housing (110) having removable bolt (116) passing therethrough. The long cylindrical body portion (118) of the bolt (116) positively abuts the relief (26) to lock the male coupler (22) in the female housing (110).
