## Abstract

A syringe adapter includes a housing having a first end and a second end with the first end configured to be secured to a first container, a cannula having a first end and a second end with the second end of the cannula positioned within the housing, and a collet having a first end and a second end. At least a portion of the collet is received within the housing. The collet includes a body defining a passageway, a membrane received by the passageway, and a locking member connected to the body of the collet. The membrane has a body with a first end and a second end. The body of the membrane defines a passageway. The collet is movable from a first position where the locking member is open to receive a mating connector to a second position where radially outward movement of the locking member is restricted.

## Claims

### Claim 1

A membrane for use in connection with a closed system transfer device, the membrane comprising:
a body having a first end and a second end, the body of the membrane defining a passageway, the body of the membrane including a first head portion and a second head portion, the first and second head portions extending radially outward from the body.

### Claim 2 (depends on 1)

The membrane of claim 1, wherein the passageway of the membrane extends from the first end of the body of the membrane towards the second end of the body of the membrane.

### Claim 3 (depends on 2)

The membrane of claim 2, wherein the passageway terminates at a position intermediate the first and second ends of the body of the membrane.

### Claim 4 (depends on 1)

The membrane of claim 1, wherein the first head portion includes a frusto-conical surface.

### Claim 5 (depends on 4)

The membrane of claim 4, wherein the second head portion includes a convex surface.
