<p>A socket (12) for removably receiving an end of a dental saliva ejector tube (10) includes a central body (24) having a first end (26) forming a port (32) for being coupled to a vacuum hose. The central body includes a passage (30) extending therethrough from the first end (26) toward a second opposing end (28). An elastic sleeve (36) is secured over the second end (28) of the central body (24) for receiving the end (22) of the dental saliva ejector tube (10). A pair of spreader members (40/42) are secured to the elastic sleeve (36). A pair of levers (44/56) are pivotally secured about the central body and are actuated by the user to pull the spreader members (40/42) apart, thereby distending the opening (38) of the elastic sleeve (36) to more easily receive the dental saliva ejector tube (10). To prevent the dental saliva ejector tube from becoming dislodged from the socket during use, a rib (66) may extend about the lower end (22) of the dental saliva ejector tube (10).</p> |
