Abstract: This combination connector and plug is for use in a sap collecting system in which plastic tubing is connected to a spout inserted in a borehole in the trunk of a tree. A member has an axial passageway for transporting sap between a first fitting for connecting a first plastic tube to the member and a second fitting for connecting a second plastic tube to the member. A projection extends from the member and is dimensioned to fit in sealing engagement in the end of the spout when the spout is removed from the borehole. With the projection placed in the end of the spout, the plastic tubing connector and spout can be stored by hanging them in a sealed condition on one of the tress from which the sap is collected.
