Abstract

The pendant tube (4), threaded (at 5), is screwed into a tapped radial opening (2) in the calibre (1). In order to allow this tube (4) to be locked on the calibre (1), its part situated square with the threading (5) is internally of nonagonal section (at 13), this providing seating for a tool formed of a rod of corresponding section. The sides of the nonagon are sufficiently close together for the circle inscribed therein to correspond to the diameter of the bushing (8) solid with the operating crown (6) which drives the stem (3) of the operating mechanism. <IMAGE>
