The secure attachment resists stress on the leaflets.

The result is a secure fastener with minimal damage to the wallboard.

Securedly held and burglarproof embodiments are described.

Locking mechanisms are disclosed for ensuring secure attachment between the interface and applicator.

Limiting with the limiting member facilitates fixing with the screw, while the screw allows for firm fixing.

The base (2) and the speaker body (1) are detachably fixed; specifically, base (2) is fixed, by means of screws, to the bottom of speaker body (1); the screws fix securely and are easily removed, making for easy use.

The base plate (14) is provided for securing to a structure (6).

The trim profiles are further provided with fastening means (54, 56) for facilitating secure attachment of the two complementary profiles to each other.

Other accessory components allow securing the case to a person or vehicle.

When the fastener reaches the steel, the minor fins have a diameter to engage and cut into the pilot bore for good grip.

These items have to be equipped with strong fixation system.

Devices (1) expand linearly to provide secure fixation between or among anatomical structures.

This invention provides a solid fixation, good stability and anatomic properties, reduced requirements concerning the mounting precision, a strong adhesion of the whole surface of the cup to the bone tissue as well as a good bone integration.

It guarantees a high-quality result and a strong fixation.

With this construction, a very strong and stable fastening has been achieved, without any high demands on dimension tolerances.
