a buckle with which said wrist strap is associated;

a housing obtained in said handgrip to house said buckle;

coupling means comprising at least one elastic tab projecting from the body of said buckle and cooperating with a corresponding support surface obtained in said housing to fix said buckle to said handgrip; and

releasing means that can be reached by the user when inserted in said housing, suitable for cooperating with said elastic tab to release said buckle from said handgrip;

wherein said housing is defined by:

a first guiding surface on which said buckle slidingly rests;

a second guiding surface opposite said first guiding surface, on which said releasing means slidingly rest; and

one pair of containing surfaces opposite each other, between which said guiding surfaces are included;

wherein in said second guiding surface there is said support surface against which said elastic tab projecting from said body of said buckle rests;

wherein said releasing means comprise a button that can be reached by the user when inserted in a top hole present in said handgrip, said button being provided with a sheet projection for releasing said elastic tab from said support surface, said sheet projection being arranged between said second guiding surface and said body of said buckle;

wherein said sheet projection projects from said button, and the releasing means further includes:

a wall that rests on said second guiding surface with one end placed in contact with said elastic tab, and

an elastic body in contact with said body of said buckle; and

wherein said elastic body is housed in a through opening made in said sheet projection and having a convex part facing towards said body of said buckle.
