The invention provides a hand release device with a parking brake unit for a rail transit vehicle and a protective sleeve of the hand release device. The protective sleeve with the parking brake unit hand relieving device for the rail transit vehicle comprises a sleeve body structure, the sleeve body structure is of a hollow cylinder structure with the two ends open, an opening is formed in one side of the sleeve body structure, and the opening extends in the axial direction of the sleeve body structure and penetrates through the two ends of the sleeve body structure; the edges, located on the two sides of the opening, of the sleeve body structure can be connected with each other so as to seal the opening. According to the hand relieving device with the parking brake unit for the rail transit vehicle and the protective sleeve of the hand relieving device, the opening is directly connected and sealed through the edges located on the two sides of the opening, compared with a zipper closing opening in the prior art, the better sealing effect is achieved, and therefore the protective effect of the hand relieving device is effectively improved; meanwhile, the structure is simple, and replacement is convenient.
