A spray can actuation device includes a body that is removably attachable to the top of a spray can. The body includes a handle and a valve actuation lever, operated by a trigger, that engages the push-button valve on the can when the trigger is pressed. A locking plate is pivotally attached to the forward portion of the body for movement between an unlocked position, in which the actuation lever is allowed to engage the valve, and a locked position, in which the lever is locked out of engagement with the valve. The forward portion of the body includes a rim that is engageable with the channel that typically surrounds the valve on such spray cans. The rim is formed by a pair of rim halves, each with a thin-walled flexure point, and joined at the front by an interlocking connection, preferably a pin-and-socket joint. During the insertion of the rim into the channel, the rim resiliently flexes at the flexure points, while the interlocking connection substantially prevents relative movement between the rim halves, thereby facilitating the attachment of the device to the can, and making the attachment more secure.
