The cable fits, as clarified previously, the Aux input of my Becker radio. Unfortunately, it does not lock, there probably was part of what Becker changed on the radio input (Radio 2006). The cable itself is well made and makes a solid impression, also at plugs. Due to lack of latching I have resorted with superglue on an unoccupied Pol. 4 stars for a technically flawless product with slight defects.
