ABSTRACT:
The closing device consists of a frame (12) and opposed arms (14) with hook (18) designed to be inserted in the central bolt (20). In the latter, which is bounded below by the base (24) and above by the crosspiece (30) there is arranged in a sliding manner the plate (28) with openings (32), (36) and (34). The latter receives the spring (42) while in the openings (32) and (36) are engaged the hooks (18) of the arms (14).
The end (28') of the plate (28) is drawn manually outward and brings about simultaneous unhooking of the arms (14) to which are constrained the band branches.
Additional forms of embodiment call for the use of a bolt (60) with pushbutton (68) for simultaneous unhooking of the arms (54) and a bolt (90) with pushbutton (98) which moves opposed shaped plates (94), (94') which constrain the arms (84).
