An umbilical cord clamp having an improved lock construction. The clamp is of generally V-shaped configuration and includes a pair of flexible arms joined together at the apex of the V by an integral hinge. One of the arms is provided at its free forward end with a flexible tongue; the other arm has a forwardly-facing recess for receiving that tongue as the clamp is closed. A pair of projections extend inwardly from opposite sides of the recess and define sloping ramp surfaces for engaging the tip of the tongue and for flexing the tongue forwardly as the arms of the clamp are squeezed into closed condition. When the clamp is fully closed, the tip of the tongue snaps into position beneath the undercut projections to lock the arms securely together. |
