The invention provides an aircraft wing (10, Fig 1), comprising a fixed wing (14, Fig 1) and a wing tip device (12, Fig 1) at the tip. The wing tip device is configurable between a locked flight configuration for use during flight and a ground configuration for use during ground-based operations. The wing further comprises a locking mechanism for locking the folding wing tip device in the locked flight configuration. A rotatable locking member 22 is associated with one of the folding wing tip device and the fixed wing, and a locking pin 32 is associated with the other. The rotatable locking member comprises a guide surface (30, Fig 2) to guide the locking pin to a locked configuration, in which the guide surface is shaped such that the locking pin is urged toward the rotation axis X of the rotatable locking member by a camming action of the guide surface on the locking pin, thereby preloading the locking mechanism.
