Keep your push‑fit plumbing connections secure with these Speedfit Collet Locking Clips. Designed to fit standard Speedfit‑style push‑fit fittings (including John Guest‑type fittings), these clips lock firmly beneath the collet to help prevent accidental pipe release caused by vibration, movement or tampering.
Suitable for both domestic and commercial plumbing installations, these clips provide added peace of mind when used on hot and cold water systems, as well as central heating pipework. Installation is quick and tool‑free — simply push the clip into place beneath the fitting’s collet for extra retention. Commonly used with stop ends and other push‑fit fittings where additional security is recommended.
All materials used in these clips are engineered to withstand sustained temperatures of up to 85°C without compromising performance. The Red & Blue mixed packs are supplied in an even 50/50 split.
