Apparatus for securing an anti-siphon device 300 in a fuel tank inlet 200; comprising a first locking portion on the inner surface of the inlet and a second locking portion, on the anti-siphon device, configured to engage the first portion; wherein a portion of the anti-siphon device is configured to inhibit the passage of a siphon tube. The locking portions may inhibit rotation between the two devices. The first locking portion may comprise a circumferentially extending groove 206 and the second locking portion may comprise a retaining ring 307 configured to be received by the groove. The retaining ring may be a split ring (figure 5) or comprise a protrusion (figure 3) corresponding to a reduced depth portion of the groove causing the prevention of rotation between the ring and anti-siphon device. There may be a second groove in the anti-siphon device configured to at least partially receive the retaining ring.
