Abstract
A device for attachment of an assembly shaft of a conveyor roller on a profile. The device includes a plate having an opening for the passage of the assembly shaft; a first clamping surface for engaging with the assembly shaft; and a first tightening hole. A tightening part includes a second clamping surface opposite the first clamping surface engaging with the assembly shaft; a second tightening hole; and a tightening member passing through the plate, the tightening part and the profile by their tightening holes. A ramp of the plate or the part causes the two clamping surfaces to approach together for clamping the assembly shaft.
