Abstract

A hand-held power tool having a main housing (4) in which a tool spindle (10) is at least partially located, and a handle housing (16) on which a handle (18) is formed, includes a connection device (28) for securing the handle housing (16) to the main housing (16) and having a first connection element (50) with a first engagement member (58) loosely engageable with a second engagement member (52) associated with the main housing (4), and a second connection element (48) with a handle-side locking element, a main housing side locking element, and a further locking element for formlockingly connecting the handle-side locking element and the main housing side locking element, whereby absence of loose engagement of the first and second engagement members is ensured upon formation of the formlocking connection of the handle-side and main housing side locking elements.
