A concrete form system includes a plurality of concrete form board brackets. The plurality of brackets includes brackets for securing the concrete form board to a conventional type metal or wood concrete form stake without the need for nails. The plurality of brackets also includes concrete form board end brackets for securing the ends of adjacent concrete form boards together that allows for a range of angles to be formed between two adjacent concrete form boards from zero degrees to more than 180 degrees. The present invention also includes flexible sections of concrete forms configured to be coupled to the brackets that allow for forming curved concrete edges.

Disclosed herein are exemplary embodiments of suture securement devices that replace the need to tie knots in sutures. Some embodiments comprise an annular outer body and one or more suture engagement tabs extending inwardly from the outer body. The devices can comprise a superelastic and/or shape-memory material and have a generally in-plane initial configuration. The suture engagement portions are deformable out-of-plane to an active configuration with the outer body compressed and the tabs interlocked with each other. The device can be heat-set in the deformed configuration. The interlocked tabs exert a pinching force on sutures passing between them that restricts the sutures from sliding through the opening in one longitudinal direction.

A clip configured for compressive engagement of fabric to pipe or similar elongated members such as those of a scaffold. The clip has a body with opposing sidewalls separated by a gap. The sidewalls are formed of elastic or flexible material which will temporarily deflect to temporarily increase the diameter of the gap, to allow passage of the pipe through the gap. The sidewalls thereafter return to the original position wherein interior surfaces of the sidewalls and an axial cavity of the body compressively engage with the pipe and any fabric adjacent thereto to hold the fabric in a compressive, sandwiched engagement between the clip and the pipe.

A clip for attaching sheeting and trim to a grain bin includes a plate having a strip that is foldable over the plate along a fold line. A pair of slots are positioned at opposite ends between the plate and the strip and extend inwardly from the ends. The strip has four corners that alternate from a 90 corner to a rounded corner.

A fastener includes a clamp arm which is connected with a base. The clamp arm cooperates with the base to form an entrance into which an article extends. A first locking tab extends from the base into a first opening in the article. A second locking tab extends from the clamp arm into a second opening in the article. When a withdrawal force is applied to the fastener, an arcuate portion of an inner side surface of the clamp arm moves from a position spaced from an outer side surface of the article to a position in which the arcuate portion of the inner side surface of the clamp arm is disposed in abutting engagement with the outer side surface of the article.
