In a releasable locking device, which is useful at a beam-to-column connection in a storage rack, a housing having a lateral wall with two parallel slots has an end wall at an outer end and is open at the inner end, a locking pin having an internal portion movable within and along the lateral wall is movable between a retracted position and an extended position, toward which the locking pin is biased, and an outer sleeve is movable outside and along the lateral wall of the housing and is connected to the locking pin via a connecting pin extending through the locking pin, through the parallel slots, at each end to the outer sleeve. The outer sleeve has an external flange to facilitate pulling of the outer sleeve to move the locking pin toward the retracted position.
