This spring clip helps to prevent your harness belt from loosening when you don't want it to. Many harness manufacturers now supply a similar spring in their harnesses from the factory. Installs in the adjuster of your 3" wide harness belt to keep tension on the adjuster bar. Sold individually.
Note: Fits American-style adjusters only. This style adjuster has a floating center bar installed in a body plate. Will not work with many newer European-style adjusters, where two or three plates are assembled and pivot against each other.
