A holder for pipe docking includes a first connector bracket and a second connector bracket. The first connector bracket includes two shells that can be relatively opened and closed. When the two shells are closed, a first accommodation space is surrounded for fixing a part of the first connector assembly of the catheter. The second connector bracket includes a base body and a cover body that can be relatively opened and closed. The base body includes a first inner casing and a first outer casing, and the cover body includes a second inner casing and a second outer casing. When the cover body and the base body are closed, a second accommodation space is surrounded by the first inner casing and the second inner casing for fixing a part of the second connector assembly of the dialysate tube. A guiding space is formed between the first inner casing and the first outer casing and between the inner casing and the second outer casing for inserting the two closed shells of the first connector bracket.一種管路對接握持器，包含第一連接器支架及第二連接器支架。第一連接器支架包含可相對開啟及閉合之兩殼體，兩殼體閉合時，圍繞出第一容置空間，以供固定輸液短管之部分第一連接器組件；第二連接器支架包含可相對開啟及閉合之基體與蓋體，基體包含第一內殼體及第一外殼體，蓋體包含第二內殼體及第二外殼體，當蓋體與基體閉合時，第一內殼體及第二內殼體圍繞界定出第二容置空間，以供固定透析液管之部分第二連接器組件，又第一內殼體與第一外殼體之間、以及第二內殼體與第二外殼體之間構成連通之導引空間，以供閉合後之兩殼體的插設對接。
