This patent discloses a pin release assembly in which a release pin and a pull pin have mating portions which interlock within a fixed collar. The interlocking surfaces of the mating portions are oriented parallel to or normal to the longitudinal axis of the pins so that no frictional side loads are produced when the interlocked pins are pulled in a direction parallel to the longitudinal axis. The release is actuated by sliding the interlocked pins within the collar. The length of travel of the release pin necessary to accomplish the desired release is coordinated with the length of travel of the mating portions within the collar so that the interlocking surfaces are pulled from the confinement of the collar at the same time as the release is accomplished, thereby permitting the pull pin and the release pin to freely separate.
