ABSTRACT:
A connector is described for joining tubes together, particularly plastics tubing as used in laboratories and the like.
The connector comprises a first member having a barb-like projection through which the tube can be pushed but cannot be pulled in the reverse direction due to the interaction between the barb-like projection and the surface of the tube. The protruding captive end of the tube passes through a resiliently deformable disc of plastics material preferably Polytetrafluroethylene and in a preferred embodiment the disc is partly housed in a cup-shaped extension from the first member.
The assembly of first member and disc is secured within a sleeve by means of a screw-thread engagement between the said first member or a further member which acts on the rear of the said first member. The said further member is screw-threadedly engaged into or onto the sleeve.
A screwdriver slot is formed at the end of the said further member and a transverse slot intersects the screwdriver slot to allow the tube extending therethrough to be pushed to one side or the other to facilitate the insertion of a screwdriver blade or the like tool.
In one embodiment the end face of the plastics disc is plain for seating against a corresponding plain end face of a similar plastics disc or seating within the sleeve. In another embodiment the sleeve is formed with two conical seatings at opposite ends joined by a throughbore and the discs are formed with complementary conical mating surfaces.
