Abstract: One or more strap holder assemblies attached to a musical instrument or like device for purposes of attaching opposite ends or predetermined portions of a strap to the instrument or device wherein a base means is fixedly attached and specifically configured to form a socket in which a swivel means is rotatably mounted. A strap connector element having a strap attachment device integrally connected thereto is pivotally mounted within the socket between certain limits which are defined by the ends of an upwardly extending and curvilinear flange which at least partially defines the socket in which the swivel means of the strap connector element and attachment device are mounted.
