A device for mounting a wheel of a bicycle on a frame, including: an inner hub rotatably mounted in a portion of the frame, an outer hub forming a central zone of the wheel, a quick-tightening mechanism that includes a male portion projecting from a first of the inner and outer hubs, a female portion provided in a second of the hubs, axial abutments for retaining the outer hub supported against the inner hub, and a mechanism for positioning the axial abutments, the positioning mechanism not being active upon completion of the tightening of the wheel. The quick-tightening mechanism is equipped with a lever that is pivoted by the operator to provide the necessary force for the axial tightening of the outer hub of the wheel against the inner hub. In a particular embodiment of the invention, the axial abutments include a plurality of balls, and the mechanism for positioning the axial abutments include ramps on which the balls roll.

A device for mounting a bicycle wheel according to claim 1, wherein: said axial abutment arrangement includes two pivotable cams retained within a bushing; said mechanism for positioning said axial abutment arrangement comprises two openings in said bushing and a spiral spring biasing the two cams to project from the bushing through said openings. 4. A device for mounting a bicycle wheel according to claim 1, wherein: said axial abutment arrangement includes cams; and said mechanism for positioning the axial abutment arrangement comprises a collar on which the cams slide. 5. A device for mounting a bicycle wheel according to claim 1, wherein: said axial abutment arrangement includes a head and a plate having an opening, the shape of said plate being complementary to a shape of said head; and said mechanism for positioning the axial abutment arrangement comprises a mechanism enabling the rotation of the head. 6. A device for mounting a bicycle wheel according to claim 1, wherein: said axial abutment arrangement includes pivotable plates forming a diaphragm; and said mechanism for positioning said axial abutment arrangement includes springs for biasing said pivotable plates to a stable resting position. 7. A device for mounting a bicycle wheel according to claim 1, further comprising: a safety device capable of preventing an accidental opening. 8. A device for mounting a bicycle wheel according to claim 1, wherein: said inner hub includes a plate having a plurality of teeth, arranged along a first circle, said teeth projecting from said plate; said outer hub also includes a plurality of teeth, arranged along a second circle having the same diameter as the first circle; and said quick-tightening mechanism is located within said first and second circles. 9. A device for mounting a bicycle wheel according to claim 1, wherein: said quick-tightening mechanism comprises a manipulation member movable between an open position prior to completion of tightening and a closed position upon completion of tightening; said device for mounting a bicycle wheel further comprising a safety device capable of preventing an accidental movement of said manipulation member to said open position. 10. A device for mounting a bicycle wheel according to claim 9, wherein: said safety device comprises means requiring a manipulation additional to movement of said manipulation member between said open and closed positions. 11. A device for mounting a bicycle wheel according to claim 1, wherein: said positioning mechanism animates said axial abutment arrangement along a radial movement. 12. A device for mounting a bicycle wheel onto a frame, said device comprising: an inner hub adapted to be rotatably mounted on a portion of the frame; an outer hub comprising a central zone of the wheel, the outer and inner hubs adapted to be retained against each other during a mounted position of the wheel on the frame; a mechanism for tightening the outer hub when retained against the inner hub, said tightening mechanism comprising: a male portion projecting from a first of said inner and outer hubs; a female portion provided in a second of said inner and outer hubs; a plurality of axial abutment elements through which force is applied for retaining the outer hub against the inner hub; a positioning mechanism to move the axial abutment elements to a position allowing the outer hub to be positioned against the inner hub and, thereby, allowing the wheel to be moved to said mounted position on the frame; a manipulation member, adapted to be manipulated by the user, having a range of movement, said range of movement comprising a first part and a second part, wherein: during said first part of said range of movement, said axial abutment elements are caused to be moved axially and radially by said positioning mechanism, thereby causing the wheel to assume said mounted position on the frame; during said second part of said range of movement, said positioning mechanism not causing movement of said axial abutment elements. 13. A device for mounting a bicycle wheel according to claim 12, wherein: said manipulation member comprises a cam-lever for axial tightening of said outer hub of the wheel against said inner hub. 14. A device for mounting a bicycle wheel according to claim 12, wherein: during said second part of said range of movement of said manipulation member, said axial abutment members are moved only axially. 15.
