Abstract (en)
[origin: EP1157790A1] The holder has radial apertures for a tool (4) with engaging elements, which is released via a control sleeve (6). A flexible holder element (8) between tool shaft and sleeve is tension by insertion of the tool, and in release position, the element prevents displacement of the sleeve in direction of a locking position, via locking elements (9). After extraction of the tool, the sleeve is moved in direction of that locking position, by hand, and in direction of the hand-held tool. The holder element is formed by a leaf spring etc.
