<p>A guide bar for a chain saw including a main bar portion having its outer end edge abutting a mating inner end edge of a nose portion. At least a section of one of the bar portions adjacent the abutting end edges is formed by side plates supported in a spaced apart position by spacing posts. A connecting web connects the bar portions with the said one bar portion fitting between the spaced apart side plates. The web is provided with slots to accommodate the supporting posts and displaceable ear portions extend into the slots to resist but not prevent passage of the posts. Forcing the said one bar portion over the web causes the ear portions to deflect around the supporting posts which then resists but does not prevent separation of said one bar portion from the web,</p> |
