to enter the space 240 when moved distally relative to the housing 202 the locks 252 254 also include levers 264 on their proximal ends opposite the fingers 256 258 the cantilevered levers 264 are positioned laterally spaced from the housing 202 so that there are spaces 266 between the levers and the housing into which the levers can be flexed flexure of the levers 264 laterally inward cause the fingers 256 258 to flex laterally outward thus permitting the connecting hub 206 to enter and exit the space 240 more easily as will be readily appreciated by one of ordinary skill in the art pulling proximally on the connecting hub 206 when positioned in the space 240 with sufficient force will also result in the fingers 256 258 spreading apart and the hub being released from the housing 202 and the locks 252 254 as illustrated in fig6 and 9 the soft cannula 204 in some aspects of the present invention is angled relative to the bottom surface 268 of the housing 202 at an angle u03b2 wherein u03b2 can be any acute angle and can be the same as a 0069 fig1 and 11 illustrate enlarged views of portions of the connecting hub 206 specifically fig1 illustrates the locks 254 including the channel 270 between the finger 258 and the housing 202 fig1 illustrates the bore 232 without the soft cannula 204 positioned in the bore fig1 13 a illustrate.
