Abstract: This disclosure generally pertains to various end pieces for releasably securing to a coupling element. In at least one example, the end piece may be used for releasably securing a guitar strap to a coupling element on a guitar. In various examples, the end piece can include a body having a first surface opposite a body having a second surface, a first aperture defining a first aperture opening communicating between the body first and second surfaces, and a plurality of resiliently flexible projection elements extending radially inward and spaced apart relation from the first aperture.

Abstract: Generally, a body having body upper face, a closed-end aperture element disposed in the body communicating with the body upper face, and a securement element affixed to the body opposite the body upper face, which can removably couple to a support surface. Specifically, a pick holder having body upper face, a closed-end aperture element disposed in the body communicating with the body upper face, which can be configured to removably retain a pick, and a suction cup affixed to the body opposite the body upper face, which can removably couple to a stringed instrument.
