A device for reducing the cross-sectional area of a capillary tube to effect its closure in a preselected region thereof. The device has a pair of means movable with respect to each other for crimping and severing the tube. First means is provided for moving the crimping and severing means pair along first and second generally orthogonal paths so as to effect alignment of the crimping and severing means pair with the capillary tube disposed therebetween, and second means is provided for moving the crimping and severing means pair along third and forth generally orthogonal paths to effect the reduction of the cross-sectional area of the tube and the severence thereof, respectively.
