A plumbing connector

A pipe connector comprising:

• a hollow body having a central throughway defining an axis, the hollow body comprising a tubular part at at least one end, the tubular part having an outer face to seal, in use, with an inner diameter of a pipe placed over the tubular part:
• a collet fitted over the tubular part of the hollow body so as to be axially fixed with respect to the hollow body and being spaced from the tubular part to form a cavity for the pipe, the inner face of the collet having at least one tooth to grip the pipe, in use, and the outer face of the collet having a first screw thread;
• and
• a locking cap fitted over the collet and having an inner face with a second screw thread which is complementary to the to the first screw thread, wherein screwing the locking cap onto the collet from an unlocked configuration to a locked configuration causes inward deflection of the collet to press, in use, the collet onto the pipe and the pipe onto the tubular part to seal the interface between the hollow body and the pipe;
• wherein in the unlocked configuration, an inner diameter of a first constriction at an open end of the collet is greater than an inner diameter of a distal part of the collet that receives the pipe.

• wherein the collet and locking cap have complementary features to produce a sound when the locking cap reaches the locked configuration.
