Abstract: A collar to secure weights on a barbell or dumbbell. Two springs are biased against a pad support on one end and against the partially closed top surfaces of cylindrical tubular casings on the other end. The radially extending legs of a grip bar connect to the pad support through the cylindrical tubular casings, allowing the pad support to raise off the barbell. A grip pad made of compressible material is disposed on the surface of the pad support and grippingly engages the barbell when the springs are fully extended, thereby securing the weights on the barbell. The collar has a substantially cylindrical housing where one end of the cylindrical housing has a greater diameter than the other end, forming a flange to secure the weights on the bar. The end of the cylindrical housing forming a flange has a fluted contact base made of a compressible material to prevent slippage between the contact base and a contiguous weight.
