A clamp for clamping and squeezing an umbilical cord, said clamp having an open configuration and a closed configuration, said clamp comprising: a first leg having an inner face comprising a clamping bed, a second leg attached at one end to the first leg at one end of said clamping bed by a resilient hinge by which the first and second legs are sprung apart, said second leg having an inner face comprising a clamping bed extending part of the length of the inner face of said second leg from the hinge attached end of said second leg, and a recessed section extending from the clamping bed of said second leg to an opposite end of said second leg; a third leg attached to said first leg at an opposite end of said clamping bed of the first leg by a resilient hinge by which the first and second legs are sprung apart, said third leg comprising a clamping bed extending the length of an inner face of said third leg, and a contact section on an outer face of said third leg; wherein said first leg, said second leg and said third leg together form a cavity capable of receiving said umbilical cord, wherein pressing said second leg towards the first leg against the resilience of the hinge joining them causes said recessed section of the second leg to contact said contact section on said third leg such that said third leg is pressed towards the first leg against the resilience of the hinge joining them, wherein said recessed section is recessed such that said third leg fits into said recessed section and is received in said recessed section when said clamp is in said closed configuration, wherein the clamping beds (18, 26) of said second and third legs (14, 22) together form a contiguous clamping bed for clamping a received object against the clamping bed of the first leg when said clamp is closed, and wherein said clamping bed of the first leg and the clamping beds (18, 26) of the second and third legs comprise a row of teeth. a first leg having an inner face comprising a clamping bed, a second leg attached at one end to the first leg at one end of said clamping bed by a resilient hinge by which the first and second legs are sprung apart, said second leg having an inner face comprising a clamping bed extending part of the length of the inner face of said second leg from the hinge attached end of said second leg, and a recessed section extending from the clamping bed of said second leg to an opposite end of said second leg; a third leg attached to said first leg at an opposite end of said clamping bed of the first leg by a resilient hinge by which the first and second legs are sprung apart, said third leg comprising a clamping bed extending the length of an inner face of said third leg, and a contact section on an outer face of said third leg; wherein said first leg, said second leg and said third leg together form a cavity capable of receiving said umbilical cord, wherein pressing said second leg towards the first leg against the resilience of the hinge joining them causes said recessed section of the second leg to contact said contact section on said third leg such that said third leg is pressed towards the first leg against the resilience of the hinge joining them, wherein said recessed section is recessed such that said third leg fits into said recessed section and is received in said recessed section when said clamp is in said closed configuration, wherein the clamping beds (18, 26) of said second and third legs (14, 22) together form a contiguous clamping bed for clamping a received object against the clamping bed of the first leg when said clamp is closed, and wherein said clamping bed of the first leg and the clamping beds (18, 26) of the second and third legs comprise a row of teeth.
