Claim 1
Independent Claim
152 words
A synthetic resin device for removably holding a plate such as a printed circuit board comprising: a main block body having a front, a back and two opposite sides; a support projection integrally connected to the lower part of the front of said main block body; a ramp catch the thin end of which is integrally connected to the upper part of the front of said main block and the thick end of said ramp catch is above said support projection, leaving therebetween a space as large as the thickness of said plate; and two or more staggered projections rising from each of the two opposite sides of said main block body and spaced apart from each other by a distance equal to the thickness of associated rising tab plates, the back of said main block body having a recess to accommodate said ramp catch when it is pushed and yieldingly sunk.
