ABSTRACT:
A conduit length adjustment device including a tubular housing slidably supporting a cylindrical slider member (24), the housing including a box-like access opening for receiving a U-shaped lock button (26). A pair of lugs (52, 54) are disposed on the exterior of the side walls (38) and each of the legs of the lock button (26) includes a pair of holes (56, 58) for co-acting with the lugs (52, 54) for defining detents for retaining the lock button (26) in unlocked and locked positions respectively. In addition, a pair of latch levers (60) extend parallel to the legs of the lock button (26) and have ramps leading to flat ends for snapping under and abutting a pair of co-acting latch abutments (62), which also have ramps (64, 66) leading to flat abutment surfaces whereby independent and simultaneous forces must be applied to the latch levers (60) and the legs of the lock button (26) to enable removal of the lock button (26) from the locked position.
