ABSTRACT:
A device for removably retaining a fluid system component in a smooth bore comprises of body on one end of which the component is mounted and the other end of which comprises a plurality of wings. The interior of the body provides female screw threads into which an expansion member is engaged, said expansion member having male screw threads at one end and at the other end a truncated conical section. Rotation of the expansion member relative to the body causes further insertion for expansion member into the body such that the conical section causes the wing members to radially expand and engage the wall of the installation bore. The device is generally cylindrical in overall configuration with an outside diameter at least slightly less than the inside diameter of the installation bore and upon retraction of the expansion member from forcible engagement with the body, the wing members relax to their original state and the device can then be readily removed from the installation bore.
