Snap-on locking clips that hold 3/8″ OD tubing firmly inside a quick-connect fitting — a simple, inexpensive safeguard against accidental tube release. 10 clips per pack.

What it does

A C-clip (also called a locking clip or collet clip) is a small horseshoe-shaped ring that snaps into the groove under the collet of a 3/8″ quick-connect fitting. With the clip in place, the collet can’t be pushed in accidentally — so the tubing stays locked and can’t pop out under pressure or if something bumps the line.

It’s a cheap, five-second upgrade that adds real peace of mind to any push-fit connection — especially on 3/8″ lines that carry higher flow rates. A surprise disconnection on a 3/8″ line means more water, faster, so locking the collet is a smart precaution. Keep a handful on hand and add one to every 3/8″ fitting.
