Abstract
A power tool having a housing divided into two parts which are interconnected by a thread joint. Internal threads are provided on the housing parts. A tubular connection element has two external axially spaced thread sections which are provided for engagement with the internal threads on the housing parts. The tubular connection element has a thin walled waist section located between the external thread sections to provide a certain elastic deformation as a tightening torque is applied on the thread joint to thereby increase the clamping length of the thread joint. A resilient ring is carried on the waist section and is arranged to be elastically deformed by squeezing between the housing parts and the connection element at tightening of the thread joint, thereby providing a rotation locking friction force on the thread joint.
