A quick release weight bar clamp comprising:
- a collar having;
- a first crescent half,
- a second crescent half,
- a hinge pivotally coupling a first end of said first crescent half to a first end of said second crescent half,
- a spreader spring moveably coupling a second end of said first crescent half to a second of said second crescent half, said spreader spring biasing said second end of said first half away from said second end of said second half, and
- a handle having;
- a handle body, and
- said handle body containing a cam configured to engage said cam follower, urging said second end of said first crescent toward said second end of said second crescent, compressing said spreader spring,
- said cam follower extending into said cam;
- a cover plate coupling said handle to said collar;
- and
- a crescent liner coupled to the inside of said first crescent half and said second crescent half.
