Dust collecting attachment

A dust collecting attachment used on a power tool having a tool body and an auxiliary handle attached to the tool body, wherein a tool bit can be coupled to a front end region of the tool body comprising:

• a dust collecting member which can be attached to the auxiliary handle in such a manner as to surround the front end region of the tool body around a longitudinal axis of the front end region in order to collect dust generated during operation by the power tool, and
• a connecting hose for connecting the dust collecting member to a dust collector,
• wherein the dust collecting member has a protrusion on one end of the dust collecting member in the longitudinal direction, and is attached to the auxiliary handle solely by axial insertion of the protrusion into a mounting hole formed in the auxiliary handle, the insertion of the protrusion into the mounting hole being configured to prevent the dust collecting member from mechanically separating from the auxiliary handle, and
• the protrusion inserted into the mounting hole is engaged with an elastic member formed on a wall surface of the mounting hole and thereby retained in an inserted position.
