A surgical instrument comprises two elongate members which are pivoted together intermediate their ends in crossing relationship, so as to define a major plane extending substantially perpendicular to the axis of pivotal movement of the members and in which the members move during relative pivotal movement thereof. Each member has at one end an operating portion which cooperates with the operating portion of the other member when the two operating portions are brought together by relative pivotal movement of the two members. Each member has at its opposite end an actuating key which can be urged towards the actuating key of the other member for bringing the operating portions into cooperating disposition. Each actuating key comprises a substantially rectangular plate which extends transversely to the major plane of the instrument whereby force can be applied to urge the actuating keys together.
