A device for collecting biological specimens having a container and a detachable handle. The handle allows a person to position the container so that contact between the person and sample is minimized or avoided. The handle includes a hoop into which the container slides from the container's lower end. The container is configured with projections on its outer surface that frictionally engage the hoop. Alternatively, the container can be configured with projections, a ring, or a lip over which the hoop is obliquely traversed to prevent the hoop from sliding downward on the outer surface of the container. The handle is constructed of a flexible material so that it may deform as needed when engaging the outer surface of the container.

1. A specimen collecting device comprising:a substantially cylindrical container for receiving a specimen, a top end of the container being open; a downward facing shoulder located on an outer surface of an upper portion of the container; an annular engagement zone extending downward from the shoulder; a detachable handle for holding the container while the specimen is collected; a hoop on the end of the handle that that slides over a lower end of the container, extends around the circumference of the outer surface of the container, wherein a top side of the hoop engages the shoulder; and wherein a retaining portion on the outer surface of the container below the shoulder has an effective outer diameter greater than an inner diameter of the hoop to selectively retain the hoop on of the engagement zone. 2. The specimen collecting device of claim 1, wherein the retaining portion comprises at least one protrusion that frictionally engages an inner diameter of the hoop when fully installed.3. The specimen collecting device of claim 1, wherein the retaining portion comprises a series of axially oriented ribs spaced around the outer surface of the container that form a frictional fit with the inner diameter of the hoop when fully installed.4. The specimen collecting device of claim 3, wherein lower portions of the ribs taper to a smaller effective outer diameter.5. The specimen collecting device of claim 3, wherein the ribs are substantially half-cylinders.6. The specimen collecting device of claim 4, wherein the ribs are substantially half-cylinders.7. The specimen collecting device of claim 1, wherein the retaining portion comprises a series of hemispherical protrusions spaced around the outer surface of the container that form a frictional fit with the inner diameter of the hoop when fully installed.8. The specimen collecting device of claim 1, wherein the retaining portion comprises a ring extending around entire circumference of the container at a lower side of the engagement zone, the ring being below the hoop when fully installed.9. The specimen collecting device of claim 1, wherein the engagement zone is a polygonal surface and the retaining portion comprises comer points of the polygonal surface, the points of the polygonal surface forming a frictional fit with the inner diameter of the hoop when fully installed.10. The specimen collecting device of claim 1, wherein the retaining portion is located at the lower edge of the engagement zone, and has an effective outer diameter greater than the outer diameter of the engagement zone;and wherein the hoop fits around the engagement zone above the retaining portion. 11. The specimen collecting device of claim 1, wherein the retaining portion comprises a series of elongated protrusions with axes perpendicular to a longitudinal axis of the container, spaced around the circumference of the container below the engagement zone, the hoop locating between the shoulder and the elongated protrusions.12. The specimen collecting device of claim 1, wherein the retaining portion comprises a series of substantially hemispherical protrusions spaced around the circumference of the container below the shoulder and separated from the shoulder by an engagement zone of lesser outer diameter than the inner diameter of the hoop, the hoop locating between the shoulder and the substantially hemispherical protrusions.13. The specimen collecting device of claim 1, wherein the retaining portion comprises a ring located below the shoulder and separated from the shoulder by an engagement zone of lesser outer diameter than the inner diameter of the hoop, the hoop locating between the shoulder and the ring.14. The specimen collecting device of claim 1, wherein the retaining portion comprises an annular lip located below the shoulder and separated from the shoulder by an engagement zone of lesser outer diameter than the inner diameter of the hoop, the hoop locating between the shoulder and the lip.15. A specimen collecting device comprising:a substantially cylindrical container for receiving a specimen, the top end of the container being open; a set of threads adjacent the top end of container; a hoop on the end of a detachable handle that that slides over a lower end of the container, and extends around the circumference of the outer surface of the container; a downward facing shoulder located on an outer surface of an upper portion of the container below the threads, the shoulder having an outer diameter greater than an inner diameter of the hoop, a top side of the hoop engaging the shoulder when fully installed; an annular engagement zone on the outer surface of the container below the shoulder for receiving the hoop; and the engagement zone having at least one protrusion located thereon that defines an effective diameter larger than the inner diameter of the hoop, the inner diameter of the hoop being in frictional engagement with the protrusion while fully installed. 16. The specimen collecting device of claim 15, wherein the at least one protrusion comprises a plurality of protrusions spaced around the circumference of the engagement zone.17. The specimen collecting device of claim 15, wherein the engagement zone comprises a polygonal surface, and the at least one protrusion comprises comer points of the polygonal surface.18. The specimen collecting device of claim 15, wherein the lower portion of the protrusion is tapered.
