Abstract: A wheel for a toy vehicle has a device whereby the wheel can be releasably and coaxially attached to a hub mounted on an axle of the toy vehicle and/or to another wheel by way of a bayonet coupling so that wheels can be easily added or removed to increase or decrease the number of wheels on any axle or to interchange wheels with different tire treads. The coupling device is supported relative to a rim of the wheel so as to be coaxial therewith and angularly movable relative thereto. The coupling device has a part on an outer side of the wheel for enabling the coupling device to be turned angularly and a first part of the bayonet coupling on the inner side of the wheel. The second part of the bayonet coupling is provided on the hub and/or a like wheel.
