Abstract
The means for securing weight plates (16) on weight rods (10′, 12) or holder bars provides at least one groove (14) formed in an end region (10′) of a weight rod (10′, 12) or in the holder bar. The weight plates (16) are formed with a radial protrusion (17) in their central bore, preferably extending over only a portion of the circumference. The diameter of the bore at the protrusion (17) is greater than the diameter of the end region (10′) of the weight rod (10′, 12) or holder bar axially next to the groove (14). The protrusion (17) falls into the groove (14) and prevents the weight plate (16) from slipping off the weight rod (10′, 12) or holder bar.
