ABSTRACT:
A method and tool (15) for securing V-shaped, open connector elements (14) o belt ends (1) in a manual operation use staples (8) that are driven by hammer blows applied to a punch held by the tool. Each connector element (14) has at least two shanks (11, 12) and at least one eye loop (13) interconnecting the shanks. The staples (8) are initially held in place for the driving by one shank (11) of the connector elements (14). The securing elements (8) first penetrate holes in one shank (11), then the belt end (1), and then holes in the shank (12), whereupon the free end pieces (53, 54) of the staples (8) are bent over in the tool provided with a die (29) for this purpose. The connecting elements (14) have downwardly projecting shanks (12) which extend initially away from the belt end. These shanks (12) are first pressed against the belt end (1) with a manually produced force increased with the aid of a tool mechanism providing a mechanical advantage. Then the staples (8) are driven by the hammer blows and finally bent over.
