Abstract
Interlocking clamps for protective shields currently available generally allow detachment from one side only. An attaching-detaching tool of this invention, by contrast, is structured with a flat edge profile (13) having a thickness less than a spacing between a supporting surface (11) of an interlocking clamp and a frame rail (1) to which the interlocking clamp is mounted. Thus, the tool can be inserted in a gap (15) between the frame rail (1) and the shield (4) and a wrench recess (16) fitted about an angled lug (8) forming a first element (5) of the interlocking clamp on a side facing away from a second clamp element (10). Wedge-shaped jaws (18 and 19), forming outwardly acute angles (17), defining the wrench recess can be pushed between the angled lug (8) of the first clamp element and forked clamping lugs (6 and 7) of a second clamp element (10). The tool allows for easy detaching of a protective shield.
