File:Anglo-Saxon sleeve clasp, Branston and Mere, Lincs. (FindID 177806).jpg

English: Anglo-Saxon sleeve clasp, gilt copper alloy, Hines Form B12. The clasp has a central flat rectangular central bar with a sunken, grooved, gilt rectanglular plate at either terminal. No silvering is visible on the central bar. One terminal plate is complete and the other incomplete. Both are gilded. Extending from the side of the central bar is a narrowed section of plate which represents the remains of a hook. Extending from the opposide side from one of the terminal plates is the remains of a loop.

This Form B12 sleeve clasp falls neatly into the 'Ruskington-Sleaford' type, as identified by John Hines (J. Hines, 1993, Clasps Hektespenner Agraffen, p47, Fig 93b). This publication lists three other examples all from the East Midlands. All three are formed of a copper alloy bar decorated in the "Bichrome Style": silvered in the centre between two sunken, grooved, gilt rectangles. One example from Glaston, Leicestershire, was discovered with a 'relatively florid cruciform brooch', which provides evidence for a 6th-century date.

Evidence from cemeteries show that sleeve clasps were usually worn by women rather than men.
