A joint formed by interconnecting a frame, a handle and a handguard with a single fastener. The members are interlocked to each other to transfer any torque created by a force applied to the housing of the chain saw or one or more of the interconnected members. The handle and the handguard each have slabbed sides which coact to produce a wedge-like locking action therebetween.
