Attaching-detaching tool

An elongated attaching-detaching tool for use with plastic interlocking clamps of a type for holding a protective shield for equipment on a frame rail, with each of the interlocking clamps comprising a first clamp element which is engaged in the frame rail and a second clamp element having two forked clamping lugs which are pushed along opposite sides of an angled lug of the first clamp element, with the shield being between the first and second clamp elements to be held therebetween, the first and second clamped elements being locked together by inter-engagement between the forked clamping lugs and the sides of the angled lug, and with the forked clamping lugs also forming a supporting surface for the shield, said tool comprising:

• an elongated flat wrench member having first and second ends, said elongated flat wrench member having a flat edge profile with a small thickness, said elongated flat member defining an open first wrench recess adjacent the first end, said open first wrench recess having an opening bounded by first and second wedge-shaped jaws forming outwardly pointed acute angles, with said open first wrench recess extending into said elongated flat member from said first and second wedge-shaped jaws toward said first end;
• whereby said wrench member can be inserted into a spacing between the supporting surface and the frame rail, and thereby into a gap between the frame rail and the shield, from a side of the shield on which the second clamp element is located and manipulated so that the angled lug of the first clamp element enters the open first wrench recess from a side of the angled lug facing away from the second clamp element, with the first and second wedge-shaped jaws being forced between the angled lug and the forked clamping lugs to spread the forked clamping lugs and cause them to release the angled lug.
