PIPE COUPLING WITH LOCKING DEVICE

摘要

The present invention concerns an aircraft pipe joint. More particularly, but not exclusively, a locking device for an aircraft pipe joint. The invention also concerns a locking device for an aircraft fuel pipe joint. An aircraft pipe coupling 20 comprises a first pipe end 22 and a second pipe end 26. The first pipe end 22 is connected to the second pipe end 26 with a fastener 24. A locking collar 10 comprises a first engagement portion 12 and a second engagement portion 14, one of the engagement portions comprising a resiliently deformable engagement surface. The first engagement portion 12 is located over and engaged with the fastener 24, and the second engagement portion 14 is located over and engaged with the second pipe end 26. The locking collar restricts the rotational movement of the first pipe end, the second pipe end, and the fastener with respect to one another.
