A valve for a bicycle tyre inflator has first and second main body parts, which slide relative to one another, and which are preferably biased, by a spring, towards a closed position. The first main body part has an opening for sealingly receiving a valve stem of a tyre to be inflated. The second main body part has a fitting to connect the valve to a compressed gas cylinder, and a stem with an internal bore and an egress aperture. The valve is closed when the egress aperture is axially located between a pair of O-ring seals surrounding the stem. Conversely, the valve is open when the first and second main body portions are slid, preferably against the action of the spring, such that the egress aperture is located axially to one side of the pair of O-ring seals, thus forming a continuous fluid pathway to permit inflation gas from the compressed air cylinder to flow into the sealingly connected valve stem.
