A connector (10) for detachably sec- uring an end of a tube, such as a catheter (20), to a fluid port (37) of a fluid transfer assembly, such as an implantable device (30), the connector having a body part (50) which defines a coupler for coupling to a coupler receiver (43) of the transfer assem- bly. The connector includes a sleeve (40) which fits within the body part and defines an aperture (46) for compressively receiving an end of the tube which has been fitted over a fluid port (37) of the transfer assem- bly. The body part is rotatable about the sleeve to facilitate coupling of the coupler and coupler receiver. In one embodiment, the connector further includes bayonet pins (54a, 54b) for twist locking the coupler in the coupling receiver. A tie down (62) may be provided to prohibit the coupler from be- ing inadvertently detached from the coup- ling receiver. A tactile indicator (55, 155) may be included to indicate correct coupling of the coupler and the coupler receiver. The sleeve generates a compressive force to secure the tube to the fluid port. A compression insert (80) may be inserted between the sleeve and tube to provide a higher degree of compression of the tube upon the fluid port. In one embodiment, the tube is a cathe- ter (120) coupled to a patient and the fluid transfer assembly (130) is an implantable device, for subcutaneous delivery of fluid to a patient in which the catheter and device have been implanted.
