The arrangement (100) includes a sap collecting device (102) and a slide clamp(104). The sapcollecting device (102) includes a tubing fixation portion (140) over whichthe free end of theflexible tubing (106) can be removably inserted with a frictional engagement.The slide clamp(104) includes an annular sleeve portion (180) that is slidingly insertableover the unexpandedouter diameter of the flexible tubing (106) and removably positionableproximate the free endof the flexible tubing (106), when the free end of the flexible tubing (106)is inserted over thetubing fixation portion (140), to constrict the free end of the flexibletubing (106) in awithdrawal-resisting frictional engagement with the tubing fixation portion(140). The slideclamp (104) also includes a plug portion (182) having an outer peripheral wallsurface (206) onwhich the free end of the flexible tubing (106) is removably insertable with africtionalengagement to prevent air and contaminants from entering.
