A tube splicing machine is provided which includes a frame on which a die holder is located. A swaging die is removably mounted in the die holder, and the die holder includes a main plate and a top plate that is removably connected to the main plate. A die holding opening is defined through a portion of the main plate and the top plate in which the swaging die is inserted. The swaging die includes two die parts that together define a die opening and are separable along a mid-line of the die opening. A splice fitting engagement plate with a splice fitting engagement portion is located on the frame, with the splice fitting engagement plate having an opening or an openable top to allow removable connection to a splice fitting. An actuator is connected between the splice fitting engagement plate and the die holder for moving the splice fitting engagement plate relative to the die holder from an initial position to a swaged position, in order to swage the splice fitting onto a length of hose or tubing. This allows a splice fitting to join quasi-endless lengths of hose or tubing in a simple manner.
