closed; 

a spring member arranged in said first handle or said second 
handle, wherein said spring member is biased between a first 

mounting point and a second mounting point; 

a lever end which is connected with one of the catching 
elements engages the spring member; 

an actuator which is in connection with said lever end for 
moving said lever end between the closed setting and the open 
setting; 

wherein said second mounting point is the point of 
engagement of the lever end which can be switched between two 
side walls within said first handle and the first catching 
element and the complementary catching element are curved 
elements wherein at least one catching element has a changing 
radius of curvature to provide a blocking element when the 
forceps is in its closed setting upon contact of the surfaces of 
the catching elements against further movement in the direction 
of openings the forceps. 

27. (previously presented) The forceps according to claim 
26, wherein the actuator is the first handle which is pivotable.
