Locking device, particularly for skate wheels

A locking device, particularly for skates constituted by a U-shaped frame comprising a first wing and a second wing having at least two wheels pivoted thereto, comprising at least one traction-operated actuation element which lies outside said first wing and is connected to a pusher which is slidingly associated with said first wing and with a pivot, said pivot being rigidly coupled to said second wing and being arranged in the interspace formed between said at least two wheels which are mutually adjacent, said wheels interacting, during compression, with at least one elastically compressible element which is coaxial to said pusher, said at least one elastically compressible element being arranged coaxially to a shank of said pusher and being interposed between the surface of said head that does not interact with the inner surface of said second wing and the inner lateral surface of said first wing said elastically compressible element being substantially H-shaped in a longitudinal cross-section.
