Cclasps

Cclasps, often written as C-clasps, are a family of fasteners characterized by a curved, C-shaped profile. They are used to join two components such as a necklace strand, bracelet, strap, or small bag element by hooking onto a post, bar, or eye and securing with a catch or friction mechanism. The term is used in jewelry, leatherwork, and accessory design to describe several related fasteners that share the general C form.

Variants of Cclasps include spring-loaded forms, which use a small spring to keep the opening closed; locking versions that require deliberate squeezing or rotation to release; and magnetic variants that rely on hidden magnets behind the curved shell. Decorative Cclasps integrate the outer C shape into the overall design, serving both functional and aesthetic roles. Materials commonly used range from metals such as stainless steel, brass, and precious metals to plastics and resins, with finishes including polished, brushed, and patinated options.

Applications for Cclasps are widespread in jewelry making, including bracelets and necklaces, as well as in leather belts, watch straps, and small bags or pouches. They are valued for a low-profile appearance and ease of use, and are popular in fashion, cosplay, and craft contexts where unobtrusive closures are preferred.

Manufacturing considerations include stamping, casting, or CNC finishing to form the C shell, and compatibility with the loop size, post, or cord diameter they are designed to secure. See also: Clasps, Jewelry fastenings, Magnetic clasps, Toggle clasps, Leathercraft hardware.
