In a key with a key bit and a handle, an end of the key bit extending in form-interlocked manner into a channel in the handle, the channel being directed towards a narrow side of the handle, the improvement comprising
- means for a disengageable insertion detent locking between said bit and handle,
- said means for detent locking comprises
- a mandrel, and
- spring means for displacing said mandrel in a direction transverse of the handle,
- said mandrel having an actuation surface exposed on a wide side of the handle,
- said key bit defining a recess extending from a narrow side of the key bit,
- a portion of the periphery of said mandrel form-interlocking into said recess.
In a key with a key bit and a handle, an end of the key bit extending in form-interlocked manner into a channel in the handle, the channel being directed towards a narrow side of the handle, the improvement comprising
- means for a disengageable insertion detent locking between said bit and handle,
- said means for detent locking comprises
- a narrow side of the key bit forming a recess, said recess being formed as an angular recess,
- a bolt which is displaceably mounted in said handle obliquely to said channel, said bolt having an end surface extending at an acute relative angle to the longitudinal direction of said channel,
- spring means for displacing said bolt such that said bolt including said end surface form-interlocks into said recess, and
- another end surface of said bolt forming substantially a V shape with said first-mentioned end surface.
In a key with a key bit and a handle, an end of the key bit extending in form-interlocked manner into a channel in the handle, the channel being directed towards a narrow side of the handle, the improvement comprising
