Abstract
An inner cylindrical member has a pair of opposing axially extending tapered slots extending toward an end distal the other proximal end to which a needle is secured for blood collecting. A pair of tabs protrude from the distal end to permit the member sides at the distal end to be squeezed together. Temporary locking projections on the inner member sides at the distal end are engaged with locking holes on an outer nested concentric cylindrical member. The squeezing action releases the temporary locking engagement. Other projections and locking ramps are on the inner member at the proximal end for engaging the locking holes on the outer member. Guide channels are in the outer member inner wall engaged with the inner member proximal projections and ramps for guiding these elements as the outer member is axially displaced from a needle use mode overlying the inner member to a needle protection mode cantilevered from the inner member.
