ABSTRACT:
A compact collar for securing weights to a barbell. The collar utilizes a spring coil, restrained against maximum tightening, thereby setting a minimum internal diameter of the coil. A pair of outwardly extending angularly displaced arms that can be moved towards each other to reduce the tightness of the coil, thereby increasing the internal diameter of the coil and permitting it to slip over the end of a barbell. Once in place, the release of the arms, allows the natural spring tendency to tighten the coil and grip the barbell, thus holding the weights in place.
