Abstract
A releasable connection device for connecting a motor driven drive cable to a closure includes a pin attached to the closure and having a head supported by a necked down stem. A cylindrical housing member has an opening in a lateral wall thereof which receives the pin. A slide member is attached to the drive cable and is reciprocably carried by the housing member. The slide member has an open ended slot smaller than the head of the pin and receiving the necked down stem. A spring acts between the housing member and the slide member to urge the members to relative positions in which the head of the pin is captured to effect a connection between the drive cable and the closure. The spring yields upon imposition of force to permit energy absorbing limited relative movement between the members and yields further to permit withdrawal of the open ended slot of the slide member beyond the head of the pin so that the pin is released from the housing member. A cam surface acts between the housing member and the head of the pin to eject the head laterally through the opening of the housing member so that the drive cable is effectively disconnected from the closure.
