Abstract
A quick-release collar is provided for securing weight plates to a weight bar in the sport of weight lifting. The collar includes a collar body defining an opening for receiving the weight bar, and defining a tangential ramp leading to the opening. A lock rod engages the ramp, and a tie rod extends through the collar to the lock rod. A handle threads onto the tie rod and, when rotated, tensions the tie rod, pulling the lock rod against the ramp into a securely wedged, interlocked engagement with the bar.
