A combination closure is provided, particularly for evacuated collection tubes for body fluids such as blood, including an elastomer stopper and plastic cover combination with cooperating locking surfaces spaced around the circumference thereof. The stopper includes vertically spaced sealing rings for insertion into the open end of the tube. Also, the stopper includes a plurality of circumferentially spaced protrusions and the cover or shield cooperating circumferentially spaced indentations or ports to provide a locking force between the pro- trusions and indentations. As a result, the dimensions of the stopper and the plastic cover are reduced, which in turn reduces the penetration force required to insert a needle through the stopper. Moreover, the reduced dimension of the closure allows it to be locked to a bead on the tube whether. plastic or glass, and the lesser overall diameter allows the closure on the tube to fit more tube holders or containers during and prior to use. In addition, the smaller dimension reduces the tendency of the closure to "rock" on the tube. The closure of the invention includes means for containing liquid droplets or aerosol when the needle is removed from the stopper.
