Claim:
A self-attaching pump attachable to a bicycle without the use of any additional device, the self-attaching pump comprising: a cylinder; a nozzle attached to the cylinder; a piston movably installed in the cylinder; a rod connected to the piston; a handle comprising a first end and a second end opposite to the first end; a fastener pivotally connecting the second end of the handle to the rod, with the handle pivotal about the fastener between an operating position and an attaching position, with the handle being parallel to the rod in the attaching position, with the handle being at a non-parallel angle to the rod in the operating position, and a stressing device arranged on the cylinder abutting with the first end of the handle in the attaching position, with the stressing device stressing the self-attaching pump when the handle is in the attaching position; wherein there are defined a first value for the distance between the fastener and the first end of the handle, a second value for the length of the stressing device when the stressing device does not stress the self-attaching pump and a third value for the distance between the piston and the nozzle when the first end of the handle in the attaching position reaches the stressing device while the stressing device does not stress the self-attaching pump, wherein the first value is larger than the second value that is larger than the third value, with the first value being parallel to the rod in the attaching position and being at a non parallel angle to the rod in the operating position, with the first end of the handle not reaching the stressing device in the operating position; and wherein the first value is larger than the second value by a difference at least equal to one half of the width of the handle.
