Twilleys 8100/0062, Stich Holder - Medium 11cm.

 Stitch holder Resembling a large safety pin, a stitch holder is used to hold stitches while they are not being worked; on a pocket lining, for example, or round a neckline when the neckband stitches will be picked up and worked later. If you have no stitch holder, thread a blunt pointed sewing needle with a generous length of contrast-coloured yarn, thread it through the stitches to be held while they are still on the needle, then slip the stitches off the needle and knot both ends of the contrast yarn.
