ABSTRACT:
A motion transmitting remote control assembly (10) includes a flexible tubular conduit (12) and a flexible core element (14) slidably disposed in the conduit (12). An end fitting (18) is molded about one end of the conduit (12) and includes an expander tip (20) with a tip rib (22). An expandable retainer (28) having a collar (34) and cantilever legs (36) extending from the collar (34), is disposed about the end fitting (18). Wedge surfaces (42) internally of the legs (36) react against the expander tip (20) and the tip rib (22) of the end fitting (18) to blossom outwardly into gripping engagement with the edges of a hole (30) in a support bracket (32). The fully-blossomed and expanded legs (36) seat behind the tip rib (22) to lock the retainer (28) in place on the end fitting (18). A retainer rib (50) is disposed within the collar (34) and attaches the retainer (28) to the end fitting (18) in an unspread, preoperative position ready for subsequent expansion and attachment to the hole (30) in the support bracket (32).
