Claim:	1. Surgical instrument comprising handles (2 , 3) articulated about a pivotal axis (4) for moving jaws, from an open position to a closed position, comprising connection means (5) which permit on the one hand, under a first pressure on the handles (2 , 3) locking the handles in a predetermined and constant position, and on the other hand, under the influence of a second pressure on said handles (2 , 3) unlocking the handles wherein an open recess (12) is provided to pass through from side to side of a thickness of the second handle (3) such that a hooking region of a catch (13), which is constituted by at least one tooth (14), is directed in a direction of a hook (9) secured to the first handle (2), and wherein the connection means (5) are constituted on the first handle (2) by an ear (6) permitting securement of the hook (9), and on the second handle (3), by the open recess (12) in which is secured the catch (13).
Claim:	2. Surgical instrument according to claim 1 , wherein the hook (9) comprises a hooking portion (10) and a resilient return portion which is constituted by a spring (11) to place said hook (9) in a same and single position when the handles are in the unlocked position.
Claim:	3. Surgical instrument according to claim 1 , wherein the ear (6) is pierced by a hole (7) to receive an axle (8) permitting the securement of the hook (9) on the first handle (2).
Claim:	4. Surgical instrument according to claim 3 , wherein the catch (13) comprises the at least one tooth (14) formed by a hollow which is delimited by a first inclined surface (15) forming an access ramp within said tooth, and by another inclined surface (16) constituting an access ramp from said tooth.
Claim:	5. Surgical instrument according to claim 4 , wherein a thickness of the catch (13) is formed by a surface (17) with a curved profile connecting the inclined surfaces (15 and 16).
Claim:	6. Surgical instrument according to claim 4 , wherein the inclined surfaces (15 , 16) are positioned in separate and parallel planes so as to facilitate sliding of a hooking portion (10) of the hook (9).
Claim:	7. Surgical instrument according to claim 2 , wherein the catch (13) is positioned and fixed within the opening recess (12) such that a bottom of a recess of the at least one tooth (14) is located within said recess (12) at a same level as a securement axle (8) of the hook (9) on the first handle (2).
