Description

ABSTRACT:
The instrument has projections with locking teeth for locking the instrument in its closed clamping position, said projections being located near the connecting zone between the levers of the instrument and their ring grips. Near one projection a slide having a wedge surface is provided, which may be shifted between the projections against spring force by pressure onto a key of the slide, for spreading appart the projections and for disengaging their locking teeth. Disengagement of the locking teeth and opening of the closed instrument are substantially facilitated by simple and inexpensive means which do not hinder operation of the instrument.
