A holder for clamping flexible sheet material includes an extruded plastic, elongated channel member having a base wall having two ends. The base wall is connected at one of the ends to a relatively short, upstanding forward leg having an inner face forming a bearing surface. The forward leg has a free upper end, and the base wall is connected at the other of the ends thereof to a relatively long, upstanding rearward leg having an upper end, and a top wall is joined to the upper end of the rearward leg. The top wall extends down behind the forward leg and has a free end which resiliently engages the bearing surface of the forward leg and it also has a crease or bend line spaced apart from the upper edge of the forward leg so as to define a wedge-shaped opening therebetween.

What is claimed is: 1. A one-piece holder for clamping a flexible sheet material, comprising: an extruded plastic, elongated channel member produced in a single extrusion of a single plastic material having a uniform durometer throughout, comprising a generally rectilinear base wall, a forward leg, a rearward leg, and a top wall each having two opposite ends, formed in situ; wherein said rearward leg and said forward leg also are generally rectilinear and are disposed generally perpendicular to said base wall with one of said ends of said rearward leg being connected to one of said ends of said base wall and one of said ends of said forward leg being connected to the opposite one of said ends of said base wall, and said other end of said forward leg defining a free end, wherein said forward leg is short relative to said rearward leg and has an inner face forming a bearing surface, and wherein one of said ends of said top wall is connected to the other of said ends of said rearward leg and the other of said ends of said top wall defines a free end, and wherein said top wall slopes downwardly from said rearward leg towards said front leg and extends down from said rearward leg to a position lying inside said forward leg and below said free end of said forward leg so that it is urged towards the inner face of the forward leg, so that its free end biasedly and resiliently engages the bearing surface of said inner face of said forward leg, thereby eliminating the necessity of further manipulation of the legs after extrusion to orient them in their proper gripping position. 2. The holder according to claim 1, further comprising: a double sided adhesive tape attached on one side to one of said base wall and said rearward leg; and a release strip detachably coupled to another side of said double-sided adhesive tape. 3. The holder according to claim 1, further comprising: a mounting clip joined to said rearward leg. 4. The holder according to claim 1, additionally comprising: a pair of end caps having at least one stanchion extending normally therefrom and wherein said rearward leg has an interior track detachably engageable by said stanchion. 5. The holder according to claim 1, wherein: said forward and rearward legs are non-orthogonal relative to said base wall. 6. The holder according to claim 1, further comprising: an inner leg adjacent said forward leg and said base. 7. The holder according to claim 6, wherein: said inner leg extends toward said rearward leg. 8. The holder according to claim 7, wherein: said top wall further includes an interior L-shaped member. 9. The holder according to claim 6, wherein: said inner leg extends toward said forward leg. 10. The holder according to claim 9, wherein: said inner leg is curved. 11. The holder according to claim 10, wherein: said inner leg is convex facing said forward leg. 12. The holder according to claim 1, wherein: said top wall includes interior means for holding a strip of printed matter. 13. The holder according to claim 12, wherein: said interior means includes a pair of L-shaped members. 14. The holder according to claim 1, wherein: said forward and rearward legs are substantially orthogonal relative to said base wall. 15. The holder according to claim 1, wherein: said top wall has a crease spaced from said free end thereof which defines an interior obtuse angle which is located substantially adjacent said free upper end of said forward leg to define therebetween a wedge-shaped opening. 16. The holder according to claim 15, wherein: said forward leg is provided with a bent segment generally adjacent its free end which is positioned substantially adjacent said crease. 17. The holder according to claim 1, wherein: said ends of said top wall, rearward leg, forward leg and base wall by which they are connected together are rounded.
