Double C Swimwear Connector – Custom Die-Cast Zinc Alloy Bikini Buckle

A small piece of hardware can completely change the look of a swimsuit. This Double C swimwear connector combines a clean rectangular frame with an interlocking C-shaped centerpiece, giving bikini straps and swimwear details a more polished, jewelry-like finish. The two side openings allow straps or fabric bands to pass through naturally, making the buckle both decorative and practical.

Made from die-cast zinc alloy, the connector has enough depth and structure to create a substantial metal look without making the design overly complicated. It works well for bikinis, one-piece swimsuits, resort wear, lingerie, and other fashion pieces where the hardware is meant to be seen rather than hidden.

Description

Why Choose Our Double C Swimwear Connectors

Basic plastic rings and sliders are easy to overlook. A custom metal connector becomes part of the design language of the swimsuit itself, adding a stronger visual identity while connecting straps or decorative fabric sections.

  • Signature Double C design — the interlocking C-shaped centerpiece creates a recognizable, jewelry-inspired detail that works especially well for premium swimwear collections.
  • Die-cast zinc alloy construction — the part is formed through die casting, allowing the rectangular frame, center motif, edges, and strap openings to be produced as one stable metal structure.
  • Designed for strap connection — openings on both sides allow elastic bands, fabric straps, or decorative tapes to pass through the buckle cleanly.
  • Three-dimensional metal appearance — compared with flat stamped pieces, die casting allows thicker profiles, rounded edges, raised motifs, and more sculpted decorative details.
  • Suitable for more than bikinis — can also be used on one-piece swimsuits, resort wear, lingerie, fashion tops, belts, and decorative garment accessories.
  • Low MOQ — suitable for independent swimwear labels, new collections, seasonal launches, sampling projects, and private-label development.
  • Fast sampling — check the buckle size, strap opening, surface finish, and overall proportion with your actual fabric before bulk production.
  • OEM & ODM ready — send us your AI files, CAD drawings, sketches, measurements, or reference images, and we can develop the connector around your swimwear design.
  • Trusted by swimwear, lingerie, and fashion accessory brands worldwide — we help brands turn decorative hardware concepts into production-ready metal components.
