1. A vessel occluder comprising:

  • (a) an elongated tubular sheath having proximal and distal ends;

    (b) a clamp member having a tubular base portion adapted to be fitted into said proximal end of said tubular sheath and having integrally formed resilient bifurcated fingers extending from said base portion, one of said fingers terminating in an integrally formed, transversely extending clasp segment having an aperture therethrough, said clasp segment being adapted to engage the other of said fingers for releasably pinching said fingers together; and

    (c) an elongated retractor adapted to extend through said aperture in said clasp segment, said tubular base portion and the lumen of said sheath and beyond both ends thereof, said retractor having a handle at its proximal end and a hook at its distal end adapted to snare the ends of a cord or the like looped about a body vessel and draw said ends through the lumen of the sheath, between said bifurcated fingers and through said aperture in said clasp segment, the arrangement being such that when said clasp segment engages the other of said fingers, said cord is restrained from axial movement with respect to said sheath.
