Abstract
A first component part (42) for a power tool has a mounting spigot (90) with a channel (239) therein and a second component part (10) of the power tool has a spigot receiving portion (54) with a rib (101) co-operable with the channel. The first component part includes a cylindrical projection with a chamfered edge (250) and the second component part includes a detent. In a first step in coupling the components parts, the channel in the mounting spigot is aligned with the co-operable rib on the spigot receiving portion. Subsequent steps include engaging the further rib of the spigot receiving portion with a channel on a side wall and finally, urging the chamfered edge past the detent.
