Universal head for mounting rubber bands in rubber-band underwater guns, characterized in that it comprises two parts or jaws (2,3) which are hinged together at one end so that they may be opened or closed in the manner of jaws and which define between them when they are closed at least one annular opening (9,10), there being provided releasable means (5,8) for locking said hinged parts (2,3) in the closed position. The said head comprises also an insert having in plan-view a profile substantially in the form of a U with the two arms (12) of the U terminating in threaded tubular bushes (13) which are joined together by a cylindrical body (14) having a diameter substantially corresponding to said circular openings (9,10) of the hinged parts (2,3), so that the cylindrical joining body (14) of said insert may be inserted inside one of said circular openings (9, 10), thus locking the joining body (14) of the two arms (12) on which said tubular bushes (13) are mounted between said jaws (2,3). <IMAGE> |
