A whistle of generally mandolin shape is adapted for adjustable mounting or seating on one's hand, wrist or forearm, or on a bulky sports glove or the like in a position facilitating convenient blowing of the whistle. A bracket is fixed generally tangentially to a generally cylindrically shaped whistle chamber portion of the whistle and has openings therethrough to receive a flexible strap that facilitates mounting of the whistle on one's hand, wrist or forearm, or on a bulky glove or the like with a mouthpiece portion of the whistle extending outwardly for convenient access for blowing. The strap defines a plurality of transverse ridges along its length that cooperate with the bracket to substantially prevent movement of the whistle along the strap when the strap is in a longitudinally taut condition.

The invention concerns a device for attaching a bell or the like to a sport hand protector or a sport glove. The device comprises a fixing part (1) which is removably or irremovably connected with a finger part (8) and on which the bell (30) or the like can be removably or irremovably mounted. The finger part (8) is removably attachable to the sport hand protector, the sport glove or the like. It is the core of the device of the present invention to provide a sportsman such as an in-line-skater with a warning device which can be easily removed from the finger or the sport hand protector so that the latter can be worn with or without said reliably fixed device and that said device can also be worn without the sport hand protector (FIG. 6A).
