A musical instrument support, having an improved slide for adjusting the length of the support and an improved clasp for engaging a musical instrument to be supported is disclosed. The slide is approximately circular in shape and is constructed in a manner to reduce the wearing of a cord which passes through the slide. This is accomplished by utilizing a sleeve which has a lower coefficient of friction than the material from which the slide is made. The cord forms two annular loops around the sleeve. The friction between the annular loops and the sleeve is sufficient to maintain the support at a given length. The clasp is constructed in a manner which reduces the number of moving parts needed to engage and disengage the musical instrument over the prior art thereby simplifying the manufacturing process. In particular, means are provided for disengaging the musical instrument from the clasp, which means comprises only a spring, two retractable jaws and a plunger having an end of predetermined extent which a support ring on the instrument may bear against, thereby compressing the spring and retracting the jaws. |
