NIPPLE FOR SPOKED WHEELS, PARTICULARLY FOR MOTORCYCLES

A nipple (1) for spoked wheels includes a head (2) and a rod (3) which are coaxial and through which a through-hole (4) extends, a manoeuvring key (5) in the head and an insert (11) of plastics material which is inserted in the hole in order to engage in a screwing manner with friction with a threaded end of a spoke. The hole comprises a threaded portion (8) which extends in the rod and a portion (12) with an increased diameter which constitutes the seat (10) for receiving the insert, the insert being formed with a tubular sleeve inserted in the seat at the side of the head and being blocked there by means of interference or adhesive bonding.
