A clamp assembly (10,110) for flexible tubing (100), having a housing (12,112) and a clamp (14,114) slidable within the housing between first and second positions, to occlude the tubing when the clamp is in the second position. Both the clamp and the housing include tubing-engaging ribs (30,60;130,160) to compress the tubing when the clamp is moved from its first or open position to its second or occluding position, with the tubing-engaging ribs being axially offset to force the tubing (100) into a tortuous path causing occlusion thereof. A pair of latch arms (62) extend forwardly from the clamp to follow respective channels (32) formed into housing side walls (20,22), with latch arm free ends (64) extending beyond the end of the housing to become latchingly engaged therewith when the clamp is moved into its occluding position, and also to be exposed to be manually engaged for delatching when desired.
