A lock for an attachment system that connects a ground engaging tool to a bucket lip. The lock is disposed, in use, between lug of a lip of the bucket and the ground engaging tool. The lock has a body, a force applying member and a force receiving member. Application of force by the force applying member causes the force receiving member to protrude from a first side of the body and to engage the lug. Relative hardnesses of the lug, the body, the force applying member and the force receiving member are such that application of a sufficiently large force via the lug to the protruding portion of the force receiving member preferentially deforms the protruding portion of the force receiving member ahead of deformation of the body or the force applying member as a preferred lock failure mode. |
