Abstract:
1. An end pin unit for attachment to a musical instrument body and adapted to secure a slotted end piece of a strap to said body, comprising: a lower pin member forming a lower shoulder; an upper pin member forming an upper shoulder; a screw for attaching one of the pin members in fixed orientation on a musical instrument body; and a rotatable connection between said one and the other pin member whereby the shoulder of the other pin member can be alternately rotated into a first mode wherein the upper and lower shoulders are aligned in a first relative orientation such that the slot can be manually passed downwardly over both of the aligned shoulders and thereby positioned beneath both shoulders and a second mode wherein the upper and lower shoulders are aligned in a different, second orientation above the slot, preventing the slot from passing upwardly over the shoulders; wherein the screw has a head and a threaded shank; the lower pin member has a pedestal portion below the lower shoulder and a central bore for threadably receiving the screw shank, whereby the screw is attachable through the lower pin member and pedestal portion to the instrument body, thereby assuming a fixed orientation of the lower shoulder relative to the instrument body when the screw is threaded into the body; and the end piece rests on the pedestal when the slot is below both shoulders.
