<p>The invention serves to hold together the male and the female parts of ground glass joints. As can be seen from the FIGS. 1,2 and 3 this new device consists of two rings (1+2) concentrically placed one above the other. Both rings are connected on their outside by three bow-shaped retainers (5). The two rings (1+2) have one opening (3,4) each on one side. These allow the rings to be slid onto the male and female parts of a glass joint. Both rings then firmly grip the two parts of the joint and hold them together.</p> |
