A removable accessory (6) such as a drawer unit can be mounted to the underside of a work surface (4) without the use of tools by engagement of a pair of front and rear slot and projection couplings (11, 12). A spring (38) automatically locks the accessory (6) to the work surface (4) when the projections (33, 41; 24) are fully engaged with the slots (14, 19). The front projection (33, 41) enters a wide portion (18) of the front slot (14) as the horizontal part (28) of the rear projection (24) enters the rear slot (19), and then a flange (41) on the front projection (33, 41) is trapped above a narrow portion (17) of the front slot (13) as the accessory (6) is pushed rearwards, and the spring (38) snaps up into its locking position against the front edge of the front slot (14). |
