Abstract
A pipe connector comprises a first pipe section having a first end and having teeth formed on its outer surface proximate to, but spaced axially apart from, the first end. A second pipe section has a second end which, in use, is to be connected to the first end of the first pipe section. A sleeve is slidably mounted on the outer surface of the second pipe section for movement between a first extended position, in which a front end of the sleeve projects beyond the second end of the second pipe section so as, in use, to overlap the first end of the first pipe section when abutted against the second end of the second pipe section, and a second retracted position in which said front end is withdrawn so as at least to be aligned with the second end of the second pipe section, the sleeve having teeth formed on its outer surface at least in the region of the front end. A stop is provided on the second pipe section and the sleeve to prevent axial movement of the sleeve beyond the extended position. A lock ring is also provided having teeth formed on its inner cylindrical surface which are sized to engage both the teeth of the first pipe section and the teeth of the sleeve when the sleeve is overlapping the first end of the first pipe section so as to lock said first pipe section and the sleeve together against relative axial movement.
