A device for fastening handles, that consists of a connecting bushing (16) and an insert (18) that are attached to both the implement (86) and to the handle (10). The insert (18), which has a rectangular cross-section, is locked into the insertion opening in the connecting bushing when a catch (62) on a leaf spring (64) engages a hole (61) in the insert. The resulting positive lock can be disengaged by a push-button (48) or sliding sleeve. The push-button (48) rests against the end (74) of the leaf spring (64) and can be used to displace the catch (62) on the leaf spring from the hole (61). An axially elastic sleeve (84) between the end of the handle and the connecting piece (20) compensates for tolerances. The circular handle merges gradually into an oval or ellipse toward the connecting piece (20).

Handling fastening device comprising: a handle including an axially extending insert opening of non-circular cross-section that extends forwardly from an open rear end of said handle; an insert having a cross-section corresponding to the non-circular cross-section of said opening, said insert including a steering surface at a forward end thereof and a locking recess in close proximity to said steering surface and rearward thereof; an axially extending leaf spring located within said handle, said spring having its rear end secured to said handle, an intermediate portion defining a cam surface and disposed obliquely with respect to a longitudinal axis of said insert opening, a locking catch surface disposed forward of said cam surface and forming an angle with respect to said cam surface, and a releasing portion forward of said catch surface; said steering surface of said insert and said cam surface of said spring cooperating in such a manner that as said insert is moved forwardly in said insert opening, said cam surface is engaged by said steering surface and causes a forward portion of said spring to deflect radially with respect to said axis and to thereby stress said spring until said catch surface and said recess are aligned, at which point said catch surface falls into said recess to lock said insert against rearward movement with respect to said insert opening; a manually operable control knob movably mounted on said handle for operatively engaging said releasing portion to deflect said spring radially in response to movement of said knob relative to said handle thereby removing said catch surface from said recess to permit said insert to be withdrawn from said recess; said catch surface and said cam surface being disposed entirely within said handle.
