ABSTRACT:
A socket for removably receiving an end of a dental saliva ejector tube includes a central body having a first end forming a port for being coupled to a vacuum hose. The central body includes a passage extending therethrough from the first end toward a second opposing end.
An elastic sleeve is secured over the second end of the central body for receiving the end of the dental saliva ejector tube. A pair of spreader members are secured to the elastic sleeve. A pair of levers are pivotally secured about the central body and are actuated by the user to pull the spreader members apart, thereby distending the opening of the elastic sleeve to more easily receive the dental saliva ejector tube. To prevent the dental saliva ejector tube from becoming dislodged from the socket during use, a rib may extend about the lower end of the dental saliva ejector tube.
