An in-line skate frame that has a main body with a transverse base equipped with at least one support surface at the toe of the boot, one support surface at the heel of the boot, two projecting lateral portions that extend the transverse base downward, and two flange portions which are adapted to receive a series of wheels. The flange portions are independent attached elements connected to the projecting lateral portions of the main body. The two projecting lateral portions each have at least one fitting formed by a groove serving as the housing of at least one zone of each flange portion, each groove being bordered by an outer wall of the projecting lateral portion and by a bracing portion common to both grooves, laterally spaced apart from one another. A frame of this type has improved properties of strength and flexural and torsional rigidity, while being simple and economical to assemble.
