<p>A nipple (1) for spokes of spoked wheels includes a head (2) which is wider than a shank (3), both of which are traversed by one axial through hole (4) which is at least partly threaded, with a seat in the head opposite the shank to house self-locking means and prevent undesired slackening of the nipple with respect to the spoke (7) when a thread (6) of the spoke is screwed into the hole, in which the seat comprises at least one recess (11) which intersects the threaded surface of the hole and the self-locking means comprise at least one insert (10) of material which is deformable in relation to the material of the nipple inserted in each recess, the recess and insert being shaped and positioned relative to the hole so that the insert is held in the corresponding recess in a position which partly projects over at least one length in the hole to interfere with the thread of the spoke.</p> |
