A disengageable belt attachment for detachably engaging a belt to an anchoring element of a portable musical instrument has an end piece anchoring the belt at an end of the belt. The anchoring element has a round head and an elongated shaft. The end piece includes a lockable coupling housing comprising a plate having a head-receiving opening, a shaft-receiving opening, a locking cover swivelably supported on the plate by a hinge on an end of the plate facing the belt, and an internal snap-in device. The locking cover is provided at its underside with a projecting locking profile formed by profile flanks projecting substantially semicircularly from the underside of the locking cover. The head-receiving opening is sized to fit over the head of the anchoring element. The shaft-receiving opening is adapted to longitudinally displace the coupling housing when the head-receiving opening is placed over the head of the anchoring element by engaging the shaft of the anchoring element. The locking cover has a closed position wherein the projecting locking profile prevents an unlocking longitudinal displacement of the coupling housing and assures a rotary coupling motion of the coupling housing around the axis of the anchoring element. The profile flanks engage the inner circumferential faces of the head of the anchoring element facing away from the shaft-receiving opening. The snap-in device locks the locking cover against an unintended opening.
