The handpiece (10) comprises squeezing means for locally and momentarily closing off the flexible tubing (13) to cut off the supply of liquid, which means consist of a movable squeezing projection (25) on a hinged control handle (17), and a stationary squeezing projection (26) secured to the body (15) of the handpiece (10).
