This invention discloses a needle retraction mechanism for a needle bearing medical device wherein a needle retaining member (31) is bonded directly to the needle (15) for selective holding of the needle (15) in a projecting configuration from the device. The needle retaining member (31) has an axial extension configured to provide at least one finger, and preferably a plurality of separable fingers (47) that are jointed about a bore. Mutual engagement between the fingers and the needle can be enhanced by adhesive or thermal bonding.
