Glossary

A Bridge Hitch Hair Pin Clip is a quick-release spring-wire retainer used to keep a hitch pin, clevis pin, or shaft from sliding out. It’s a variant of the common hair-pin (R-clip) where the straight leg passes through the cross-hole in the pin and the curved leg snaps over the outside diameter. The “bridge” is an arched hump formed near the head of the clip; it increases spring force, gives finger clearance, and helps the clip seat positively against the pin so it’s less likely to shake loose under vibration.

How it works: push the straight leg through the pin’s hole until the bridge rides against the pin or shoulder. The curved leg flexes and clamps the pin’s OD, creating a friction hold. To remove, pull on the bridge and slide the clip out—no tools required. It’s reusable and designed for frequent on/off use.

Where used: trailer couplers and drawbars, agricultural/landscaping equipment, lawn & garden attachments, material-handling fixtures—any place a hitch or clevis pin needs a fast, secure keeper that tolerates vibration.

Options & sizing: made from spring steel wire (typically zinc-plated) or stainless for corrosion resistance; available in light-duty to heavy-duty wire diameters and lengths to match common pin sizes. Choose a clip size specified for your pin diameter; replace if bent, cracked, or if spring tension feels weak.
