Abstract
A housing having a channel is provided with a slotted, elastomeric valve body dividing the channel. The slotted valve body is biased in the closed position by a metal spring. If the valve body's material loses resiliency, the spring guarantees that the valve takes its closed position, even if the valve body is kept in the opened state for a considerable span of time by a steel cannula inserted through the valve body.
