Fixing system for carrier bags for motorcycles

A carrier bag provided with a system for hooking and unhooking said carrier bag with respect to the tank of a motorcycle, the system comprising a first group of components suitable to be fixed to the carrier bag and a second group of components suitable to be fixed to the tank, characterised in that said first group of components comprises a flexible ring provided with a plurality of locking teeth elastically projecting inwards of said flexible ring, said locking teeth coupling with an annular flange of said second group of components to obtain the hooking of the carrier bag to the tank, a hand-driven mechanism for radial retraction of said locking teeth being provided for on the flexible ring to generate a radial displacement of said locking teeth, allowing disengagement between said flexible ring and said annular flange and, hence, obtaining the disengagement of the carrier bag from the tank;

• and further characterised in that said first group of components comprises a plate, constrainable to the carrier bag, and that said flexible ring is constrained to said plate by interposing an annular connection element, said flexible ring being free to rotate with respect to said annular connection element.
