Provided on a rig (1) for a sailboard (3) is a fastening device for fastening a wishbone head (17) to a mast (5) of the rig (1). The fastening device comprises a mast sleeve (21) which is anchored to the mast (5) and to which the wishbone head (17) is releasably fastened. In order to provide a means of fastening the wishbone (13) to a mast (5) in such a way that a wishbone head (17) can be fastened with free play to the mast (5) without any expenditure of force and can be dismantled, provision is made for the wishbone head (17) to be releasably held on the mast sleeve (21) via a swivel lock (15) in such a way that the wishbone (13) can be released from its anchorage only in the untrimmed state after swivelling approximately in a direction parallel to the mast (5) (Fig. 3). <IMAGE>
