A fluid collection device is provided having a first cylinder and a second cylinder slidably supported by the first cylinder. At least a portion of the first cylinder flexibly engages the second cylinder to retard relative axial motion of the cylinders. A needle may be mounted to an inner surface of the first cylinder. Upon flexible engagement, the cylinders may contact in a sliding frictional engagement to retard axial motion. The first cylinder may include at least one flexible tab. |
