ConvaTec DuoLock Curved Tail Closure Clamps

For anyone managing a drainable ostomy pouch, the closure is the part that has to be trusted every single time. The ConvaTec DuoLock Curved Tail Closure Clamp is engineered to secure the tail of your drainable pouch with a positive, audible click — so you know it's shut without second-guessing. Its curved shape follows the natural contour of the body, sitting flatter and more discreetly under clothing than a rigid straight clamp.

The DuoLock clamp (reference 175652) is designed for use with ConvaTec drainable pouches, including the SUR-FIT Natura®, Esteem synergy®, ActiveLife®, and SUR-FIT® systems. If you already wear one of these pouches, this is the matched replacement clamp — no adapters or workarounds needed.

Why the closure clamp matters day to day

A worn, cracked, or hard-to-open clamp is one of the most common reasons for leaks and skin irritation. Clamps take repeated bending, and the locking mechanism can loosen over time, which is why many wearers keep spares on hand and replace them periodically rather than waiting for a failure. The DuoLock's dual-lock design gives two points of security, and the curved profile makes opening and closing easier for those with limited dexterity — a real consideration for anyone managing their pouch several times a day.

These clamps are reusable and washable, so a single clamp lasts through many pouch changes, but keeping a backup in a travel kit or bathroom drawer means you're never caught without a working closure.
