ABSTRACT:
A quick disconnect dual stud type of track tie-down fitting for use with a track having slots and lips includes an insert having a generally U-shaped body and including spaced integral legs arranged in parallel alignment. Cooperating with the insert is a retainer having apertures therein which receive the legs of the insert, the ends of the legs carrying studs which pass through the slots of the track and which can engage the lips of the track. Carried by the retainer and located between the studs is a locking nub which secures the tie-down fitting in the track by being received within a slot thereof while the studs are engaged with lips of the track adjacent to the slot. The retainer is biased into the locking position by springs cooperating with the legs of the insert to urge the retainer into the locking position. By forming the insert as an integral U-shaped member, the cost of the unit is substantially reduced while the overall structure is vastly simplified.
