PURPOSE: Provided is an attachment device for a backpack shoulder strap that can be used to hold a variety of different implements. CONSTITUTION: An attachment device for a strap, comprises a base (10), means (11-14) for attaching the base to a shoulder strap of a backpack and a releasable catch mechanism for securing an implement holder. The invention further comprises at least one implement holder adapted to be releasably secured to the base (10) via the releasable catch mechanism. The releasable catch mechanism comprises an upwardly extending side wall (19) extending up from the top surface of the base and having an overhanging lip (20). A flexible arm (21) is integrally formed with the base near the side wall and has a free end extending above the plane of the base. The implement holder comprises a plate, a holder portion attached to the top surface of the plate and an attachment portion extending from the bottom surface of the plate. The attachment portion comprises an outwardly extending flange. The implement holder is coupled to the base by inserting the flange underneath the overhanging lip (20). The flexible arm (21) exerts upward pressure on the flange and forces it against the lip (20) to hold it in place. The implement holder is released from the base by pressing down on the flexible arm (21) and sliding the flange out from the lip.
