Abstract: A two-piece expanding lock control cable end fitting for connecting a co-axial cable assembly with a support structure. The first piece is a sleeve that is attached, typically by crimping, to the conduit member. The second part is a lock clip member. The lock clip member includes a base flange, a cylindrical portion and an inclined portion. During assembly the base flange on the clip member will contact the mating part and prevent the clip member from traveling through the mating part. The mating part could be a backing plate, a frame member, or brake lever component. When the clip member stops traveling through the mating part, the sleeve continues to move through the clip member. The end of the sleeve contacts the inclined portion of the clip member causing the clip member to expand. When the sleeve it is fully seated in the clip member, a locking feature on the clip member engages the sleeve to prevent removal of the sleeve from the clip member.
