A system for securing interlocking tubular components comprises first and second tubular components (1,2) to be secured and a locking apparatus (3) located within the first tubular component (1). The first tubular component (1) has a smaller diameter than the second component (2) and contains slits (5) that permit expansion of the outer diameter of the first tubular component (1) under the action of the locking apparatus (3). Each of the first and second tubular components (1,2) has an aperture (22,4) therein, the locking apparatus (3) having a spring-loaded button member (6) that protrudes from the aperture (22) of the first component (1). When the first component (1) is inserted into the end of the second component (2), the apertures (22,4) are aligned and the button (6) rises through the second aperture (4), thus holding the components (1,2) together. An adjustment tool is then inserted through a bore (17) in the button (6) into the locking apparatus (3). The turning of the adjustment tool pushes apart clamping members (8,9) in the apparatus (3) which in turn increases the diameter of the first component (1), thereby firmly holding the two components (1,2) together. <IMAGE> |
