A retainer for a bag shoulder strap, including a flat longitudinal member having a retaining portion on one end, a pin retaining member secured to one side of the flat longitudinal member, and a pin member. The pin retaining member defines a transverse space between the retaining member and the longitudinal member adjacent the longitudinal member other end, and also includes wings spaced from the longitudinal member and projecting inwardly from opposite sides adjacent the longitudinal member one end. The pin member includes a transverse portion pivotally trapped in the transverse space, and first and second pin legs extending longitudinally from opposite ends of the transverse portion to pointed ends adjacent the longitudinal member one end. In a securing position the pointed ends of the pin legs are between the pin retaining member wings and the longitudinal member.
