ABSTRACT:
A motion transmitting remote control assembly (10, 10') of the type for transmitting motion in a curved path by a motion transmitting core element and including an adjustment mechanism for adjusting the length of either the conduit (14) or the core element (12) along the longitudinal axis. The adjustment mechanism includes a fitting member (26), opposed and radially outwardly tapered conical sections (16) are disposed within the fitting member (26), and a pair of ramp collets (18) are normally in wedging engagement with the conical sections (16) for radial expansion into engagement with the fitting member (26) to create radial binding forces between the conical sections (16) and the fitting member (26) to prevent axial movement of the fitting member (26) relative to the conical sections (16) along the longitudinal axis in an adjusted fixed position. The collets (18) are axially movable relative to the conical sections (16) to a release position for releasing the radial binding forces to allow the fitting member (26) to be moved axially relative to the conical sections (16) along the longitudinal axis. Tabs (34) support posts (38) which extend radially into grooves (36) in the collets (16) for disengaging the gripping engagement to allow axial adjustment.
