Abstract
Conduits (3a, 3b, 3c) are joined with a one-piece tubular connecting piece (1) by inserting support members (5a, 5b, 5c) through a sealable opening (6) in the connecting piece to support the conduit ends while said ends are secured to the connecting piece to communicate with openings (4a, 4b, 4c) in the connecting piece. After securing the conduit ends to the connecting piece, the support members are withdrawn through the sealable opening and that opening is then sealed. The support members can also act as electrodes for welding the conduit ends to the connecting piece, especially when the conduit ends and connecting piece are formed of thermoplastics. The method has particular, but not exclusive, application to smoothly connecting tubes for conveying blood.
