The main part defines a central opening, first and second side portions, first and second end portions, first and second pairs of projection portions extending from the first and second end portions, respectively, a first notch defined by the first pair of projection portions, and at least a first end friction surface formed at a juncture of one projection portion of the first pair of projection portions and the first end portion. The bar defines a bar notch. The first side portion pivotably supports the bar for rotation between a first position in which the bar is not in contact the second side portion and a second position in which the bar notch receives the second side portion.
