Abstract
A tool holder for a power tool, in particular a drilling and/or hammering tool comprising a manually actuable sleeve () wherein components of the tool holder are held within the sleeve by a snap ring () which snap ring is fitted within the sleeve. The snap ring has at least one resilient arm () and the sleeve has a corresponding number of through holes () which extend to a radially outwardly facing surface of the sleeve, arranged such that the or each arm is engageable with a corresponding through hole in a snap fit. Each arm and through hole cooperate so that the portion () of the or each arm which can be viewed from the radially outwardly facing surface of the sleeve appears in the shape of a symbol. Thus, the snap ring () has the dual function of maintaining components, such as a locking ring () within the sleeve () and of providing an external indication to a user of how to actuate the sleeve.
