Abstract
A ferrule for connecting two adjacent components is provided, wherein the ferrule defines an exterior wall portion having a plurality of asymmetrical dimples. Each asymmetrical dimple has at least two sidewalls, and one sidewall defines a first ramp angle, and the other sidewall defines a second ramp angle that is steeper than the first ramp angle. At least one feature of one of the adjacent components engages the plurality of asymmetrical dimples such that the sidewall with the first ramp angle provides less force in an engaging direction and the sidewall with the second ramp angle provides more force in a disengaging direction.
