Abstract
The locking device for a pliers-shaped tool, preferably a pair of pliers (1), has a lever (7) with a spring (8a) on the inner side of one handle and a shaped rod (9) on the inner side of the other handle (4b). The shaped rod (9) has a catching element (10) and passes through an opening (14) in the lever (7). The lever has a sharp projection (15) in its opening (14), which engages the catching element (10) of the shaped rod (9) in the closed setting in such a way that the pliers (1) can only be closed. With these pliers (1), objects (5) can be gripped, held tight and let loose again. The locking device is entirely between the handles (4a and 4b) of the pliers (1). The pliers (1) with the locking devices can be used generally, but their primary application is in surgery.
