Swivel Snap (Dog Clip)

A sprung clip with a 360-degree swivel eye, used to clip a strap, key or charm to a bag or belt and let it rotate freely. The body is a stamped, wire-formed or cast metal part with a bought-in spring; Qinxi has no stamping, cold-heading or spring line, so the whole fitting is sourced from the supply chain.

Applications

  • BackpacksClip for the sternum strap or an accessory loop
  • Crossbody bags
  • HandbagsCharm or tassel clip on the strap
  • BeltsTool or accessory clip

Selection tips

  • Match the eye and gate size to what it clips: too small and the strap will not pass, too large and it rattles.
  • Specify the spring strength against the load; a weak spring opens under its own weight, a strong one is hard to operate.
  • Ferrous versions trigger garment needle detectors; for 100% needle-detected markets use brass or non-magnetic stainless.
  • EU skin-contact items need nickel-free plating to meet REACH nickel-release limits.

Manufacturing process & quality control points

Qinxi in-houseSupply chain / partnersIn-house or supply chain
  1. 1

    Stamping / wire forming / casting of the body

    Supply chain / partners

    The clip body is blanked, bent or cast and the gate is machined. Qinxi has no stamping, cold-heading or casting line, so this is done by the supply chain to the agreed dimensions and plating.

    Quality control points

    • Body dimension and gate finish · Caliper and 10x loupe · Per lot, AQL 2.5 (ISO 2859-1 general level II)
  2. 2

    Spring fit and plating

    Supply chain / partners

    A bought-in spring is fitted and the part is plated. Plating is outsourced to the supply chain; coating thickness and corrosion are verified against the agreed specification.

    Quality control points

    • Spring action and gate closure · Manual open/close cycle x20 · Per lot, AQL 2.5 (ISO 2859-1 general level II)
    • Coating thickness · XRF coating thickness gauge (ISO 3497 / ASTM B568) · One set per plating colour per batch
  3. 3

    Swivel smoothness and pull test

    Supply chain / partners

    The swivel eye is rotated and the clip is pulled to an agreed load to confirm the eye does not bind and the gate does not open under load. Supplied and tested by the supply chain, with Qinxi spot-checking.

    Quality control points

    • Swivel rotation and pull-to-load · Rotate by hand + universal tensile machine, 50 mm/min · One sample set per batch
